Address Status
(Processor)
Synchronous Address Status from Processor. ADSP is an active LOW input that is used to load the
address registers with new addresses. ADSP is gated by CE.
Synchronous Address Advance. ADV is an active LOW input that is used to advance the internal burst
counter, controlling burst access after the initial address is loaded. When the input is HIGH the burst
counter is not incremented; that is, there is no address advance.

Synchronous byte write enable gates the byte write inputs BW1-BW4. If BWE is LOW at the rising edge of
CLK then BWx inputs are passed to the next stage in the circuit. If BWE is HIGH then the byte write inputs
are blocked and only GW can initiate a write cycle.

NOTES:
1. VIH (max) = VDDQ + 1.0V for pulse width less than tCYC/2, once per cycle.
2. VIL (min) = -1.0V for pulse width less than tCYC/2, once per cycle.
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VDD terminals only.
3. VDDQ terminals only.
4. Input terminals only.
5. I/O terminals only.
6. This is a steady-state DC parameter that applies after the power supplies have
ramped up. Power supply sequencing is not necessary; however, the voltage
on any input or I/O pin cannot exceed VDDQ during power supply ramp up.
7. TA is the "instant on" case temperature

NOTES:
1. R5 can either be directly connected to VDD, or connected to an input voltage ≥ VIH, or left unconnected.
2. These pins are NC for the "S" version or the JTAG signal listed for the "SA" version. Note: If NC, these pins can either be tied to VSS, VDD or left floating.
3. T7 can be left unconnected and the device will always remain in active mode.
4. TRST is offered as an optional JTAG Reset if required in the application. If not needed, can be left floating and will internally be pulled to VDD.

NOTES:
1. H1 can either be directly connected to VDD, or connected to an input voltage ≥ VIH, or left unconnected.
2. These pins are NC for the "S" version or the JTAG signal listed for the "SA" version. Note: If NC, these pins can either be tied to VSS, VDD or left floating.
3. H11 can be left unconnected and the device will always remain in active mode.
4. Pins P11, N6, B11, A1, R2 and P2 are reserved for 9M, 18M, 36M, 72M, 144M and 288M respectively.
5. TRST is offered as an optional JTAG Reset if required in the application. If not needed, can be left floating and will internally be pulled to VDD.

NOTES:
1. All values are maximum guaranteed values.
2. At f = fMAX, inputs are cycling at the maximum frequency of read cycles of 1/tCYC while ADSC = LOW; f=0 means no input lines are changing.
3. For I/Os VHD = VDDQ - 0.2V, VLD = 0.2V. For other inputs VHD = VDD - 0.2V, VLD = 0.2V.

NOTES:
1. Measured as HIGH above VIH and LOW below VIL.
2. Transition is measured ±200mV from steady-state.
3. Device must be deselected when powered-up from sleep mode.
4. tCFG is the minimum time required to configure the device based on the LBO input. LBO is a static input and must not change during normal operation.

Description
OPCODE
Forces contents of the boundary scan cells onto the device outputs(1).
Places the boundary scan register (BSR) between TDI and TDO.
EXTEST
0000
Places the boundary scan register (BSR) between TDI and TDO.
SAMPLE allows data from device inputs(2) and outputs(1) to be captured
in the boundary scan cells and shifted serially through TDO. PRELOAD
allows data to be input serially into the boundary scan cells via the TDI.
SAMPLE/PRELOAD
0001
Loads the JTAG ID register (JIDR) with the vendor ID code and places
the register between TDI and TDO.
DEVICE_ID
