User manual
19.10.5.2 Master States
19.10.5.3 State: 0x08
19.10.5.4 State: 0x10
19.10.6.1 State: 0x18
19.10.6 Master Transmitter states
State 0x08 and State 0x10 are for both Master Transmit and Master Receive modes. The
R/W bit decides whether the next state is within Master Transmit mode or Master Receive
mode.
A START condition has been transmitted. The Slave Address + R/W bit will now be
transmitted.
A repeated START condition has been transmitted. The Slave Address + R/W bit will now
be transmitted.
Previous state was State 0x08 or State 0x10, Slave Address + Write has been transmitted,
ACK has been received. The first data byte will be transmitted.
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 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. 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
