Bit | Fields | Access | Default Value | Description |
---|---|---|---|---|
31:10 | Reserved | N/A | 0x0 | Reserved |
9 | STA | W | N/A | 1: Requests a repeated START condition to be generated before current byte transfer |
8 | STO | W | N/A | 1: Requests a STOP condition to be generated after current byte transfer |
7:1 | AD | W | N/A | When in address phase, these fields act as address bits When in data phase with the core is configured as a host transmitter, these fields represent I2C data bit [7:1] of the data byte to be transmitted by the core. When in data phase and the core acts as host receiver, this field is not used |
0 | RW_D | W | N/A | When transfer is in address phase, this field is used to specify the direction of I2C transfer 0: Specifies I2C write transfer request 1: Specifies I2C read transfer request When transfer is in data phase with core is configured as a host transmitter, this field represents I2C data bit 0 of the data byte to be transmitted by the core. When transfer is in data phase and the core acts as host receiver, this field is not used |
