BK3231S Datasheet
V1.5
3.2 Interrupt and Clock Unit
The MCU core clock can be selected from three clock sources: 32KHz clock, 16
MHz clock and 96 MHz DPLL.
The ARM968E-S supports two interrupt level. The FIRQ has higher priority than
nIRQ. In the BK3231S, all peripheral interrupts are nIRQ except the Bluetooth
transceiver. All interrupt can be enabled, disabled, and cleared. There are two
low power modes: MCU stop and deep sleep, and any interrupt can be
configured to be a wake up source to let MCU exit low power mode.
3.3 GPIO
There are totally 40 general purpose input/output ports (GPIO). All the 40 ports
can be used for general I/O with selectable direction for each bit, or these lines
can be used for specialized functions.
3.4 ADC
An 8bits SAR-ADC is integrated in the BK3231S. Total 8 channels can be
selected used for ADC transfer. The ADC supports continue mode and single
transfer mode, and the sample rate can be 1 KHz to 32KHz. In single transfer
mode, it will generate interrupt every time after transform.
The ADC has four work modes they are sleep mode, single mode, and software
mode and continue mode.
IDLE mode(mode==00): ADC is in idle state.
Single mode(mode==01): The ADC will enter idle mode when transfer is done
and waiting MCU to read the result. You should write mode=1 again for another
transfer.
Controlled by software (mode==10): In this mode, interrupt will be triggered after
transfer and wait MCU to read. The interrupt will be cleared after MCU read, and
then the transfer will start again.
Continue mode(mode==11):The ADC will work at the sample rate set by register.
The sample rate can be calculated by the next formula:
F_sample = input ADC clock/(2^(ADC_CLK_RATE+2) / 36(or 18))
The highest sample rate is 32k

BK3231S Datasheet
V1.5
The local interrupt flag of ADC need not be cleared by software; it will be set after
transform and be cleared after the result has been read out. But the ADC
INTstored ICU should be cleared after the ADC INT service finished.
The range of input voltage is from 0v to 1.5V. If the input voltage more than 1.5V,
a resistor can be added to decrease the input voltage like the next diagram.

Note: There are eight GPIO can be ADC input. When used as this:
Voltage=data [9:0]/448; the saturate voltage is 1.5 volt.
3.5 UART
The UART interface has 128 bytes FIFO for both TX and RX. It will generate
interrupt request when there is risk or event of FIFO underflow or overflow. For
the RX, it will generate interrupt if found parity bit check error or stop bit check
error.
When the UART RX line goes from idle state (‘HIGH’) to active state (‘LOW’) for
a set UART clock cycle, it will generate wake up interrupt to activate MCU clock.
3.6 I2C-SMBus
The I2C I/O interface is a two-wire, bi-directional serial bus. The I2C is compliant
with the System Management Bus Specification, version 1.1, and compatible with
the I C serial bus. Reads and writes to the interface by the system controller are
byte oriented with the I2C interface autonomously controlling the serial transfer of
the data.
Data can be transferred at up to 1/10th of the system clock as a master or slave
(this can be faster than allowed by the I2C specification, depending on the
system clock used). A method of extending the clock-low duration is available to
accommodate devices with different speed capabilities on the same bus.

Page 18 of 24
BK3231S Datasheet
V1.5
The I2C interface may operate as a master and/or slave, and may function on a
bus with multiple masters. The I2C provides control of SDA (serial data), SCL
(serial clock) generation and synchronization, arbitration logic, and START/STOP
control and generation.
It is assumed the reader is familiar with the I2C-Bus Specification -- Version 2.0
and system Management Bus Specification -- Version 1.1.
The bi-directional SCL (serial clock) and SDA (serial data) lines must be
connected to a positive power supply voltage through a pull-up resistor or similar
circuit. Every device connected to the bus must have an open-drain or open-
collector output for both the SCL and SDA lines, so that both are pulled high
(recessive state) when the bus is free.
3.7 SPI
The Enhanced Serial Peripheral Interface (SPI) provides access to a flexible, full-
duplex synchronous serial bus. SPI can operate as a master or slave device in
both 3-wire or 4-wire modes, and supports multiple masters and slaves on a
single SPI bus. The slave-select (NSS) signal can be configured as an input to
select SPI in slave mode, or to disable Master Mode operation in a multi-master
environment, avoiding contention on the SPI bus when more than one master
attempts simultaneous data transfers. NSS can also be configured as a chip-
select output in master mode, or disabled for 3-wire operation. Additional general
purpose port I/O pins can be used to select multiple slaves.
There are four pins for SPI interface. The master-out, slave-in (MOSI) signal is
an output from a master device and an input to slave devices. It is used to
serially transfer data from the master to the slave. This signal is an output when
SPI is operating as a master and an input when SPI is operating as a slave. Data
is transferred most-significant bit first. When configured as a master, MOSI is
driven by the MSB of the shift register in both 3- and 4-wire mode.
The master-in, slave-out (MISO) signal is an output from a slave device and an
input to the master device. It is used to serially transfer data from the slave to the
master. This signal is an input when SPI is operating as a master and an output
when SPI is operating as a slave. Data is transferred most-significant bit first.
The MISO pin is placed in a high-impedance state when the SPI module is
disabled and when the SPI operates in 4-wire mode as a slave that is not
selected. When acting as a slave in 3-wire mode, MISO is always driven by the
MSB of the shift register.

V1.5
In slave mode, the data on MOSI are sampled at the middle of period of every bit.
In master mode, the data on MISO are sampled at the last clock period to
acquire the maximal setup time.
3.8 PWM Timer
There are three timers, two of which is 16 bit and can be works as PWM waveform
generator, while the other one is 20bit timer. The PWM waveform can be output to GPIO
to drive external device such as LED.
3.9 Watch dog
The watch dog is used to reset the whole chip when the firmware runs out of order.
