Input and Output Polarity Control

SPIxCON1 has three bits that control the polarity of the SPI inputs and outputs:
For all three bits, when the bit is clear, the input or output is active-high, and when the bit is set, the input or output is active-low. When the EN bit is cleared, SS_out and SCK_out both revert to the Inactive state dictated by their polarity bits. The SDO Output state, when the EN bit is cleared, is determined by several factors as follows:
