C Master Transmit Status Codes
If 10-bit addressing is being used, then the status code is
a 10-bit address, plus the write bit, are successfully transmitted.
After this interrupt is serviced and the second part of the 10-bit address is transmitted, the
I2Cx_SR register contains one of the codes in
Microprocessor Response
For a 7-bit address: Write a
byte to DATA, clear IFLG
Or set STA, clear IFLG
Or set STP, clear IFLG
Or set STA & STP, clear IFLG
For a 10-bit address: Write an
extended address byte to
DATA, clear IFLG
Same as code 18h
