Arbitration has been lost in Slave Address + R/W bit as bus Master. General call has been
received and ACK has been returned. Data will be received and ACK returned. STA is set
to restart Master mode after the bus is free again.
Previously addressed with own Slave Address. Data has been received and ACK has
been returned. Additional data will be read.
Previously addressed with own Slave Address. Data has been received and NOT ACK
has been returned. Received data will not be saved. Not addressed Slave mode is
entered.
Previously addressed with General Call. Data has been received, ACK has been returned.
Received data will be saved. Only the first data byte will be received with ACK. Additional
data will be received with NOT ACK.
4. Initialize Slave data counter.
5. Exit
1. Write 0x24 to CONSET to set the STA and AA bits.
2. Write 0x08 to CONCLR to clear the SI flag.
3. Set up Slave Receive mode data buffer.
4. Initialize Slave data counter.
5. Exit
1. Read data byte from DAT into the Slave Receive buffer.
2. Decrement the Slave 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 Slave Receive buffer pointer.
8. Exit
1. Write 0x04 to CONSET to set the AA bit.
2. Write 0x08 to CONCLR to clear the SI flag.
3. Exit
1. Read data byte from DAT into the Slave Receive buffer.
2. Write 0x0C to CONCLR to clear the SI flag and the AA bit.
