7.4.3 Pulldown Register B
Pulldown register B inhibits the pulldown devices on port B pins
programmed as inputs.
NOTE:
If the SWPDI bit in the mask option register is programmed to logic 1,
reset initializes all port B pins as inputs with disabled pulldown devices.
PDIB[3:2] — Pulldown Inhibit B Bits
PDIB[3:2] disable the port B pulldown devices. Reset clears
PDIB[3:2].
1 = Corresponding port B pulldown device disabled
0 = Corresponding port B pulldown device not disabled
