Software module of M3L-bus by using HS-SSC for C16x microcontroller family.

Unspecified 

Software module of M3L-bus by using

HS-SSC for C16X uC family

void M3lInit()

Initialize the port and serial communication. P3.7 - I2CEN, P3.13 - SCLK, P3.8 & P3.9 -

SDA. Configure the synchronous channel to the baud rate of 1.0 MBaud. Pull-up

resistors are required for SCL and SDA lines.

Parameter

None

Description

unsigned char M3lStart()

Generate a start condition on M3L bus. Before that, check the data line for any bus faulty

like no pull-up resistor on SDA or pull-down to low by the slave device. The time-out for

data line is approximately 10 ms before the start of M3L protocol.

Parameter

None

Description

Return

The return value is “0” if the clock and data lines have no problem. Otherwise, the return

value will be “1”.

void M3lMasterWrite(unsigned char input_byte)

Output one byte of data to the slave device. Before that, check for any WAIT condition.

Parameter

unsigned char input_byte

Description

one byte of data to be sent to slave.
