SS
1 I/O CMOS SPI1 module Slave Select Control pin
1) Used to enable transmit/receive in Slave mode,
if SSEN (SPI1CON<7>) has been set to ‘1’
2) Used as Frame Sync I/O Pulse when FRMEN and
SPIFSD (SPI1CON<14:13>) are set to ‘11’ or ‘10’.
SS2
I/O CMOS SPI2 module Slave Select Control pin
1) Used to enable transmit/receive in Slave mode,
if SSEN (SPI2CON<7>) has been set to ‘1’
2) Used as Frame Sync I/O Pulse when FRMEN
and SPIFSD (SPI2CON<14:13>) are set to ‘11’ or ‘10’.
Legend: CMOS = CMOS compatible input or output, ST = Schmitt Trigger input with
CMOS levels, I = Input, O = Output
