PORTB FUNCTIONS AND OUTPUT
PRIORITIES
Each PORTB pin is multiplexed with other functions. The
pins, their combined functions and their output priorities
are briefly described here. For additional information,
refer to the appropriate section in this data sheet.
When multiple outputs are enabled, the actual pin
control goes to the peripheral with the lowest number in
the following lists.

1. SEG0 (LCD)
2. CCP4, 28-pin only
3. RB0
RB1
1. P1C (ECCP1), 28-pin only
2. RB1
RB2
1. P1B (ECCP1), 28-pin only
2. RB2
RB3
1. CCP2/P2A
2. RB3
RB4
1. COM0
2. P1D, 28-pin only
3. RB4
