PIN DESCRIPTIONS

Each PORTB pin is multiplexed with other functions. The

pins and their combined functions are briefly described

here. For specific information about individual functions

such as the SSP, I2C or interrupts, refer to the appropriate

section in this data sheet.

6.3.4.1

RB0/AN12/CPSB8/INT

These pins are configurable to function as one of the

following:

• General purpose I/O

• Analog input for the ADC

• Capacitive sensing input

• External edge triggered interrupt

6.3.4.2

RB1/AN10/CPSB9

These pins are configurable to function as one of the

following:

• General purpose I/O

• Analog input for the ADC

• Capacitive sensing input

6.3.4.3

RB2/AN8/CPSB10

These pins are configurable to function as one of the

following:

• General purpose I/O

• Analog input for the ADC

• Capacitive sensing input

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7-0

ANSB<7:0>: Analog Select between Analog or Digital Function on Pins RB<7:0>, respectively

0 = Digital I/O. Pin is assigned to port or digital special function.

1 = Analog input. Pin is assigned as analog input(1). Digital input buffer disabled.

Note 1:

When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to

allow external control of the voltage on the pin.
