SS1
1 I TTL Slave select input for MSSP1 module.
Legend: O = Output, I = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Buffer Input, TTL = TTL Buffer Input,
x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).
Note 1: Implemented on 100-pin devices only.
