RF5/AN10/CV
REF RF5 0 O DIG LATF<5> data output; not affected by analog input. Disabled when
CV
REF output is enabled.
1 I ST PORTF<5> data input; disabled when analog input is enabled.
Disabled when CV
REF output is enabled

RF7 0 O DIG LATF<7> data output.
1 I ST PORTF<7> data input.
SS
1 I TTL Slave select input for MSSP (MSSP 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).
