Output
Note 1: The SSx
pin must be used for Slave mode operation when CKE = 1.
2: When the SSEN (SPIxCON1<7>) bit is set to1’, the SSx
pin must be driven low so as to enable transmission and
reception in Slave mode.
3: Transmit data is held in SPIxTXB and SPIxTBF remains set until all bits are transmitted.
4: Operation for 8-bit mode shown; the 16-bit mode is similar.
