PIC16(L)F720/721
REGISTER 6-12: TRISC: PORTC TRI-STATE REGISTER
R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1
TRISC7 TRISC6 TRISC5 TRISC4 TRISC3 TRISC2 TRISC1 TRISC0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘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
REGISTER 6-13: ANSELC: ANALOG SELECT REGISTER FOR PORTC
R/W-1 R/W-1 U-0 U-0 R/W-1 R/W-1 R/W-1 R/W-1
ANSC7 ANSC6 — — ANSC3 ANSC2 ANSC1 ANSC0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
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.
