Slave Select Mode
The SS pin allows a synchronous slave mode. The SPI must be in slave mode
(SSPCON<3:0> = 04h) and the TRIS bit must be set the for the synchronous slave mode to be
enabled. When the SS pin is low, transmission and reception are enabled and the SDO pin is
driven. When the SS pin goes high, the SDO pin is no longer driven, even if in the middle of a
transmitted byte, and becomes a floating output. If the SS pin is taken low without resetting SPI
mode, the transmission will continue from the point at which it was taken high. To clear the bit
counter the Basic SSP module must be disabled and then re-enabled. External pull-up/pull-down
resistors may be desirable, depending on the application.
To emulate two-wire communication, the SDO pin can be connected to the SDI pin. When the
SPI needs to operate as a receiver the SDO pin can be configured as an input. This disables
transmissions from the SDO. The SDI can always be left as an input (SDI function) since it cannot
create a bus conflict.
