Writes to PORTB are actually written to corresponding LATB register. Reads from PORTB register is
return of actual I/O pin values.
Global WPUEN bit of the OPTION register must be cleared for individual pull-ups to be enabled.
The weak pull-up device is automatically disabled if the pin is in configured as an output.
RB<7:0>: PORTB I/O Pin bit
1 = Port pin is > V
0 = Port pin is < V
LATB<7:0>: PORTB Output Latch Value bits
WPUB<7:0>: Weak Pull-up Register bits
1 = Pull-up enabled
0 = Pull-up disabled
