REGISTER 19-3: TRISGPA: PORTGPA TRI-STATE REGISTER
R/W-1 R/W-1 R-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1
TRISA7 TRISA6 TRISA5 TRISA4 TRISA3 TRISA2 TRISA1 TRISA0
bit 7 bit 0
Legend:
R = Readable bit P = Programmable 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 TRISA<7:6>: PORTGPA Tri-State Control bit
1 = PORTGPA pin configured as an input (tri-stated)
0 = PORTGPA pin configured as an output
bit 5 TRISA5: GPA5 Port Tri-State Control bit
This bit is always ‘1’ as GPA5 is an input only
bit 4-0 TRISA<4:0>: PORTGPA Tri-State Control bit
1 = PORTGPA pin configured as an input (tri-stated)
0 = PORTGPA pin configured as an output
REGISTER 19-4: WPUGPA: WEAK PULL-UP PORTGPA REGISTER
U-0 U-0 R/W-1 U-0 R/W-1 R/W-1 R/W-1 R/W-1
— — WPUA5 — WPUA3 WPUA2 WPUA1 WPUA0
bit 7 bit 0
Legend:
R = Readable bit P = Programmable 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 Unimplemented: Read as ‘0’
bit 5 WPUA5: Weak Pull-up Register bit
1 = Pull-up enabled.
0 = Pull-up disabled.
bit 4 Unimplemented: Read as ‘0’
bit 3-0 WPUA<3:0>: Weak Pull-up Register bit
1 = Pull-up enabled.
0 = Pull-up disabled.
Note 1: The weak pull-up device is enabled only when the global RAPU
bit is enabled, the pin is in input mode
(TRISGPA = 1), and the individual WPUA bit is enabled (WPUA = 1), and the pin is not configured as an
analog input.
2: GPA5 weak pull-up is also enabled when the pin is configured as MCLR
in Configuration word.
