10.12.6 Master Transmitter states
A Repeated START condition has been transmitted. The Slave Address + R/W bit will be
transmitted, an ACK bit will be received.
Previous state was State 8 or State 10, Slave Address + Write has been transmitted, ACK
has been received. The first data byte will be transmitted, an ACK bit will be received.
Slave Address + Write has been transmitted, NOT ACK has been received. A STOP
condition will be transmitted.
Data has been transmitted, ACK has been received. If the transmitted data was the last
data byte then transmit a STOP condition, otherwise transmit the next data byte.
5. Set up Master Receive mode data buffer.
6. Initialize Master data counter.
7. Exit
1. Write Slave Address with R/W bit to I2DAT.
2. Write 0x04 to I2CONSET to set the AA bit.
3. Write 0x08 to I2CONCLR to clear the SI flag.
4. Set up Master Transmit mode data buffer.
5. Set up Master Receive mode data buffer.
6. Initialize Master data counter.
7. Exit
1. Load I2DAT with first data byte from Master Transmit buffer.
2. Write 0x04 to I2CONSET to set the AA bit.
3. Write 0x08 to I2CONCLR to clear the SI flag.
4. Increment Master Transmit buffer pointer.
5. 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. Decrement the Master data counter, skip to step 5 if not the last data byte.
2. Write 0x14 to I2CONSET to set the STO and AA bits.
3. Write 0x08 to I2CONCLR to clear the SI flag.
4. Exit
5. Load I2DAT with next data byte from Master Transmit buffer.
