35.3 Host Mode
In Host mode, the device controls the SCK line and, as such, initiates data transfers and determines when any clients broadcast data onto the SPI bus.
- Full Duplex mode
- Receive Only mode
- Transmit Only mode
- Transfer Off mode
The modes are illustrated in the following table:
TXR = 1 | TXR = 0 | |
---|---|---|
RXR = 1 | Full Duplex mode BMODE = BMODE =
| Receive Only mode Transfer when RxFIFO is not full and the Transfer Counter is nonzero Transmitted data are either the top of the FIFO or the most recently received data |
RXR = 0 | Transmit Only mode BMODE = BMODE = Received data are not stored | No Transfers |
