19.4.1.7 SPI Receive Only Operation

Setting the DISSDO control bit (SPIxCON1[12]) disables transmission at the SDOx pin. This allows the SPI module to be configured for a Receive Only mode of operation. The SDOx pin will be controlled by the respective port function if the DISSDO bit is set.

The DISSDO function is applicable to all SPI operating modes.
