Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-0
TRISC<7:0>: PORTC Tri-State Control bits
1 = PORTC pin configured as an input (tri-stated)
0 = PORTC pin configured as an output

bit 7-6
ANSC<7:6>: Analog Select between Analog or Digital Function on Pins RB<7:6>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input⁽¹⁾. Digital input buffer disabled.
bit 5-4
Unimplemented: Read as ‘0’
bit 3-0
ANSC<3:0>: Analog Select between Analog or Digital Function on Pins RC<3:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input⁽¹⁾. Digital input buffer disabled.
Note 1: Setting a pin to an analog input automatically disables the digital input circuitry. Weak pull-ups, if available,
are unaffected. The corresponding TRIS bit must be set to Input mode by the user in order to allow external
control of the voltage on the pin.
