4.3 Clock / Reset
4.3.1 Clocks
The TC6371AF has two pins for input clocks: PCICLK and CLK32.
(1) PCICLK: PCI clock input (33 MHz max)
PCI interface and internal operation reference clock.
(2) CLK32: 32-kHz clock input
Used as detecting insertion and removal of SD card and SmartMedia and an interrupt detection clock
and for event detection in D3 state. The interrupt signal, implied insertion or detachment, shall be
generated synchronous to this clock signal. Note that if CLK32 is stopped, the interrupt detector does
not operate while TC6371AF is suspended or in D1-3 state set according to the PCI bus power
management interface specifications.
4.3.2 Reset
The TC6371AF uses the following two reset signals.
(1) #PCIRST: PCI reset signal. Asserted at power on and at a transition to D3cold. When the input
destination of this signal is set to D3 state, the contents of the context register are saved and not
cleared even when #PCIRST is asserted.
(2) #PWRST: Power-on reset signal. Asserted at power on. Asserting #PWRST clears all the TC6371AF’s
internal registers.

4.4 Detection of Insertion/Removal of SD Card/ SmartMediaTM
4.4.1 Detection of Insertion/Removal of SD Card
The TC6371AF detects insertion and removal of the SD card using #SDCD and SDCD3. When #SDCD is Low or
SDCD3 is High, the SD card is inserted. When #SDCD is High or SDCD3 is Low, the SD card is withdrawn.
The following is an example of how to detect insertion of the SD card.
1. The TC6371AF detects that #SDCD is Low, then turns power on to the SD card socket.
2. The TC6371AF detects that the SDCD3 pin is High.
The following is an example of how to detect removal of the SD card.
1. The TC6371AF detects that #SDCD is High, or SDCD3 is Low.
2. The TC6371AF turns power off.
* Removing the SD card while the card is being accessed may damage the card.
The SD card insertion/removal status can be checked by bit 9, 8, 4, and 3 of 1Ch SD port register.
4.4.2 Detection of Insertion/Removal of SmartMediaTM
The TC6371AF can detect insertion and removal of the SmartMediaTM using #SMCD and #SMEJSW. When
#SMCD or #SMEJSW is Low, the SmartMediaTM is inserted. When #SMCD or #SMEJSW is High, the
SmartMediaTM is withdrawn. When the bit 7 of the SmartMediaTM host controller configuration register 63h set
to “1” and when #SMEJSW is High, this indicates that the SmartMediaTM is inserted. When the bit 6 of
SmartMediaTM host controller configuration register 63h set to “1”, detection of SmartMediaTM has been masked
using #SMEJSW.
The following is an example of how to detect insertion of the SmartMediaTM
1. The TC6371AF detects that #SMCD is Low, then #SMEJSW is Low.
2. The TC6371AF then turns power on to the SmartMediaTM socket.
.
The following is an example of how to detect removal of the SmartMediaTM
.
1. The TC6371AF detects that #SMEJSW is High, then #SMCD is High.
2. The TC6371AF then turns power off.
* Removing the SmartMediaTM card when the SmartMediaTM is being accessed may damage the SmartMediaTM
.
The SmartMediaTM insertion status can be checked using status bits 3 and 2 and interrupt status bit 3 of the
SmartMediaTM control register.

4.5 Interrupts
When the TC6371AF detects the following interrupt sources, the TC6371AF asserts interrupt signals (#INTA,
#INTB, #PME). The power management register has to be set in order to get #PME output.
4.5.1 Interrupt Sources by SD Card
Interrupt sources by the SD card are as listed below:
Normal interrupts
• SD card insertion interrupt by #SDCD *
• SD card removal interrupt by #SDCD *
• SD card insertion interrupt by SDCD3 *
• SD card removal interrupt by SDCD3 *
• Interrupt by write enable buffer signal
• Interrupt by read enable buffer signal
• Interrupt by R/W end signal
• Interrupt by response end signal
Error interrupts
• Timeout error (command) interrupt
• Buffer underflow interrupt
• Buffer overflow interrupt
• Timeout error (data) interrupt
• End bit error interrupt
• CRC error interrupt
• CMD index error interrupt
4.5.2 Interrupt Sources by SmartMediaTM
Interrupt sources by the SmartMediaTM are as listed below:
• SmartMediaTM insertion interrupt
• SmartMediaTM removal interrupt
• Interrupt by #SMEJSW signal
• Interrupt when #SMRB signal changes from Low to High
* Interrupt sources which can be output to #PME. Other interrupt sources can only be output to #INTA or #INTB.

controller configuration register at 62h. In Manual Power Supply Control mode, bits 3 and 2 of the
SmartMediaTM control register (offset: 02h) are used. In Automatic Power Supply Control mode, when the
SmartMediaTM is inserted, power is automatically turned on. When the SmartMediaTM is removed, power is
turned off.
As of January. 2002, the SmartMediaTM driver uses a manual power supply control.

• Phase I: Immediately after power on, #PCIRST and #PWRST are L and #SUSPEND is H. This state clears
all circuits.
• Phase II: Normal state with #PCIRST de-asserted (H).
• Phase III: Asserting #SUSPEND sets suspend state. In this state, TC6371AF prevents throughput of
signals input from the SD card and SmartMediaTM.(*) In this state, TC6371AF cannot accept PCI
transactions. Stopping the PCICLK in suspend state reduces power consumption.
• Phase IV: De-asserting #SUSPEND restores TC6371AF to its normal operating state.
*
When #SUSPEND is Low, TC6371AF prevents current flow from VCC to GND even if an intermediate
potential is applied and TC6371AF masks out the input buffer signals as well.

4.8.4 #PME Generation
#PME is controlled (enabled/disabled) by the bit 8 (PME_EN) of the power management control/status register
(config offset: 84h). The status can be checked using the bit 15 of the register. When the TC6371AF detects card
insertion/removal events or other interrupt events, the TC6371AF asserts #PME. The host controller controls
registers to perform masking events and controlling flags.

Note:
The TC6371AF uses a 32-kHz clock (CLK32) for the #PME control circuit.
In D3hot/D3cold state or in D1/D2 state where the CLKRUN protocol operates, PCICLK is stopped.
Therefore, when CLK32 is not input, the TC6371AF’s #PME control circuit does not operate and #PME
cannot be supported.
4.8.5 #PME Pin
The #PME pin outputs power management interrupts according to PCI bus power management interface
specifications. Because the pin is an open drain output determined by PCI bus power management interface
specifications, it must be pulled up outside the TC6371AF. To prevent leak current from the external pull-up
even when the power supply to this pin is off, the pin is open-drain output with failsafe measures.

• Phase I: #PWRST and #PCIRST are L when the VCC is turned on from power off. This state clears all
circuits, including the PME context.
• Phase II: Normal operating mode. #PWRST and #PCIRST are both H.
• Phase III: Setting PMCSR (config 84h) bits 1 and 0 to 11b sets the internal circuitry to D3hot. The PCICLK
is set to L except at a configuration access of PMCSR. Setting bits 1 and 0 of PMCSR to 00b shifts to
D0uninit state. Asserting #PCIRST at L shifts to Phase IV D3cold.
• Phase IV: Asserting #PCIRST at L sets the internal circuitry to D3cold. During this period, the power
supply to VCC can be switched to Vaux. At that time, VCCP can be turned off, but because #PCIRST is L
and #PWRST is H, the PME context is saved.
• Phase V: VCCP is turned back on and PCICLK goes active. While #PCIRST is L, an internal (general) clear
resets all circuits except the PME context. Next, the TC6371AF returns to normal operating mode and
the context can be written.

・If D3cold is supported, it is desirable to switch Vaux after asserting #PCIRST. When restoring from D3cold state,
make sure that the PCICLK waveform is stable.

4.8.7 Vaux in D3cold State
Because the TC6371AF supports a D3cold state, it requires an auxiliary power supply (Vaux). The four systems
that need the auxiliary power supply are:
• TC6371AF internal PME context (includes interrupt detection): VCC
• Card slot power supply (power-SW) related control: VCC
• Interface with host (system interface): VCC
• SmartMedia™ slot/SD card slot interface: VCC
Toshiba recommends asserting #PCIRST to be “Low" before moving to Vaux operation.

4.9 Serial ROM Interface
The TC6371AF supports a serial ROM interface. The ROM interface is used to load the configuration register
initial values (mainly subsystem ID and subsystem vendor ID initial values) and CIS information when using the
CardBus card.
When using the serial ROM interface, connect the interface as below and set the external pins TST1[3-0] to
D010.
Toshiba verified operation of the serial ROM interface using one ”NM93C66”(Fairchild) with a 10-kΩ resistor
connected shown as the figure below.
