10.12.7 Master Receive states
Data has been transmitted, NOT ACK received. A STOP condition will be transmitted.
Arbitration has been lost during Slave Address + Write or data. The bus has been
released and not addressed Slave mode is entered. A new START condition will be
transmitted when the bus is free again.
Previous state was State 08 or State 10. Slave Address + Read has been transmitted,
ACK has been received. Data will be received and ACK returned.
Slave Address + Read has been transmitted, NOT ACK has been received. A STOP
condition will be transmitted.
Data has been received, ACK has been returned. Data will be read from I2DAT. Additional
data will be received. If this is the last data byte then NOT ACK will be returned, otherwise
ACK will be returned.
6. Write 0x04 to I2CONSET to set the AA bit.
7. Write 0x08 to I2CONCLR to clear the SI flag.
8. Increment Master Transmit buffer pointer
9. Exit
1. Write 0x14 to I2CONSET to set the STO and AA bits.
2. Write 0x08 to I2CONCLR to clear the SI flag.
3. Exit
1. Write 0x24 to I2CONSET to set the STA and AA bits.
2. Write 0x08 to I2CONCLR to clear the SI flag.
