The RB0 pin is multiplexed with the A/D converter ana-
log input 4 and the external interrupt input (RB0/AN4/
INT). When the pin is used as analog input, the ANSEL
register must have the proper value to select the RB0
pin as Analog mode.

The RB1 pin is multiplexed with the A/D converter ana-
log input 5 and the MSSP module slave select input
(RB1/AN5/SS). When the pin is used as analog input,
the ANSEL register must have the proper value to
select the RB1 pin as Analog mode.

Upon RESET, the ANSEL register config-
ures the RB1 and RB0 pins as analog inputs.
Both RB1 and RB0 pins will read as ’1’.
