Slave Select Mode
When in slave select mode, the SS pin allows multi-drop for multiple slaves with a single
master. The SPI must be in slave mode (SSPCON<3:0> = 04h) and the TRIS bit, for the
SS pin, must be set for the slave select mode to be enabled. When the SS pin is low, trans-
mission 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. External pull-up/ pull-down resistors may be desirable, depending on the
application.
When the SPI is in Slave Mode with SS pin control enabled, (SSPCON<3:0> = 0100) the SPI
module will reset if the SS pin is set to V
set, then the SS pin control must be enabled.
When the SPI module resets, the bit counter is forced to 0. This can be done by either by forcing
the SS pin to a high level or clearing the SSPEN bit
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.
