0: Disables Ten Bit Address Match.
1: Enables Ten Bit Address Match.
Slave address used in slave address match. Bits 9:0 are used if in 10-bit mode, bits 6:0 otherwise.
0: Does not stretch bus clock after address match.
1: Stretches bus clock after address match.
0: Causes NBYTES to count down (decrement) per byte transferred.
1: Causes NBYTES to count up (increment) per byte transferred.
0: Causes a low value to be returned in the ACK cycle of the data phase in slave receiver mode.
1: Causes a high value to be returned in the ACK cycle of the data phase in slave receiver mode.
0: Disables SMBus PEC (CRC) generation and check.
1: Enables SMBus PEC (CRC) generation and check.
0: Causes the TWIS not to acknowledge the SMBus Host Header.
1: Causes the TWIS to acknowledge the SMBus Host Header.
0: Causes the TWIS not to acknowledge the SMBus Default Address.
1: Causes the TWIS to acknowledge the SMBus Default Address.
0: Causes the TWIS to release the SMBALERT line and not to acknowledge the SMBus Alert Response Address (ARA).
1: Causes the TWIS to pull down the SMBALERT line and to acknowledge the SMBus Alert Response Address (ARA).
This bit will always read as 0.
Writing a zero to this bit has no effect.
