PIC16C6X
The SS pin allows a synchronous slave mode. The
SPI must be in slave mode (SSPCON<3:0> = 04h)
and the TRISA<5> bit must be set the for synchro-
nous 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 mid-
dle 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. 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.
