Global RABPU bit of the OPTION register must be enabled for individual pull-ups to be enabled.
The weak pull-up device is automatically disabled if the pin is in Output mode (TRISA = 0).
The RA3 pull-up is enabled when configured as MCLR and disabled as an I/O in the Configuration Word.
WPUA<5:4> always reads ‘1’ in XT, HS and LP Oscillator modes.
Global Interrupt Enable (GIE) must be enabled for individual interrupts to be recognized.
IOCA<5:4> always reads ‘1’ in XT, HS and LP Oscillator modes.
Unimplemented: Read as ‘0’
WPUA<5:4>: Weak Pull-up Register bit
1 = Pull-up enabled
0 = Pull-up disabled
Unimplemented: Read as ‘0’
WPUA<2:0>: Weak Pull-up Register bit
1 = Pull-up enabled
0 = Pull-up disabled
Unimplemented: Read as ‘0’
IOCA<5:0>: Interrupt-on-change PORTA Control bit
1 = Interrupt-on-change enabled
0 = Interrupt-on-change disabled
