REGISTER 12-7: PORTC: PORTC REGISTER
U-0 U-0 R/W-x/u R/W-x/u R/W-x/u R/W-x/u R/W-x/u R/W-x/u
— — RC5 RC4 RC3 RC2 RC1 RC0
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 RC<5:0>: PORTC General Purpose I/O Pin bits
1 = Port pin is >
VIH
0 = Port pin is < VIL
REGISTER 12-8: TRISC: PORTC TRI-STATE 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
— — TRISC5 TRISC4 TRISC3 TRISC2 TRISC1 TRISC0
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 TRISC<5:0>: PORTC Tri-State Control bits
1 = PORTC pin configured as an input (tri-stated)
0 = PORTC pin configured as an output
REGISTER 12-9: LATC: PORTC DATA LATCH REGISTER
U-0 U-0 R/W-x/u R/W-x/u R/W-x/u R/W-x/u R/W-x/u R/W-x/u
— — LATC5 LATC4 LATC3 LATC2 LATC1 LATC0
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 LATC<5:0>: PORTC Output Latch Value bits

Note 1: Writes to PORTC are actually written to corresponding LATC register. Reads from PORTC register is
return of actual I/O pin values.
