O = Output, I = Input, ANA = Analog Signal, DIG = CMOS Output, ST = Schmitt Trigger Buffer Input,
x = Don’t care (TRIS bit does not affect port direction or is overridden for this option)
Alternate pin assignment for T0CKI on 64-pin devices when the T0CKMX Configuration bit is cleared.
Default pin assignment for T3CKI on 64-pin devices when the T3CKMX Configuration bit is set.
Unimplemented on 28-pin devices. Read as ‘ 0 ’.
