Datasheet
IIC Control Register 2 (IICC2, $C3
Note1: Read and Writer’0’ only
Note2: Read only
Note3: Read and Writer
SRW: The Slave Rw bit will indicate the data direction of IIC protocol. It is updated after the calling address is received
MRW: This MRW bit will be transmitted out to be the bit 0 of the calling address when the module sets the MAS TER bit

the module is in master receive mode. When it is zero, the module is in master transmit mode. Reset clears this

SDA and SCL lines (after current ACK bit) and send out the calling address which is stored in the IICADR
register. But if the TFIF flag is set when transmit fail occurs on the lines, the module will discard the master
mode by clearing the MASTER bit and release bit SDA and SCL lines immediately. This bit will be cleared
automatically after generate a start condition to the SDA and SCL lines. Reset clears this bit.
Note: clock source is from external (12M Hz).
