Write this bit to zero to disable Ten Bit Address Match.
Write this bit to one to enable 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.
Writing this bit to zero will not strech bus clock after address match.
Writing this bit to one will strech bus clock after address match.
Writing this bit to zero causes NBYTES to count down (decrement) per byte transferred.
Writing this bit to one causes NBYTES to count up (increment) per byte transferred.
Writing this bit to zero causes a low value to be returned in the ACK cycle of the data phase in slave receiver mode.
Writing this bit to one causes a high value to be returned in the ACK cycle of the data phase in slave receiver mode.
Writing this bit to zero disables SMBus PEC (CRC) generation and check.
Writing this bit to one enables SMBus PEC (CRC) generation and check.
Writing this bit to zero causes TWIS not to acknowledge the SMBus Host Header.
Writing this bit to one causes TWIS to acknowledge the SMBus Host Header.
Writing this bit to zero causes TWIS not to acknowledge the SMBus Default Address.
Writing this bit to one causes TWIS to acknowledge the SMBus Default Address.
Writing this bit to zero causes TWIS to release the SMBALERT line and not to acknowledge the SMBus Alert Response
Address (ARA).
Writing this bit to one causes TWIS to pull down the SMBALERT line and to acknowledge the SMBus Alert Response Address
(ARA).
