TABLE 12-4: SUMMARY OF REGISTERS ASSOCIATED WITH PORTC
(1)
REGISTER 12-10: ANSELC: PORTC ANALOG SELECT REGISTER
U-0 U-0 U-0 U-0 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1
— — — — ANSC3 ANSC2 ANSC1 ANSC0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-4 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: When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to
allow external control of the voltage on the pin.
REGISTER 12-11: WPUC: WEAK PULL-UP PORTC REGISTER
U-0 U-0 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1
— — WPUC5 WPUC4 WPUC3 WPUC2 WPUC1 WPUC0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-6 Unimplemented: Read as ‘0’
bit 5-0 WPUC<5:0>: Weak Pull-up Register bits
1 = Pull-up enabled
0 = Pull-up disabled
Note 1: Global WPUEN
bit of the OPTION register must be cleared for individual pull-ups to be enabled.
2: The weak pull-up device is automatically disabled if the pin is in configured as an output.
