11.11.8 Slave Receiver states
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 DAT. Additional
data will be received. If this is the last data byte then NOT ACK will be returned, otherwise
ACK will be returned.
Data has been received, NOT ACK has been returned. Data will be read from DAT. A
STOP condition will be transmitted.
Own Slave Address + Write has been received, ACK has been returned. Data will be
received and ACK returned.
3. Exit
1. Write 0x14 to CONSET to set the STO and AA bits.
2. Write 0x08 to CONCLR to clear the SI flag.
3. Exit
1. Read data byte from DAT into Master Receive buffer.
2. Decrement the Master data counter, skip to step 5 if not the last data byte.
3. Write 0x0C to CONCLR to clear the SI flag and the AA bit.
4. Exit
5. Write 0x04 to CONSET to set the AA bit.
6. Write 0x08 to CONCLR to clear the SI flag.
7. Increment Master Receive buffer pointer
