Preliminary
LATB<0> data output.
PORTB<0> data input. Weak pull-up available only in this mode.
External interrupt 0 input.
Enhanced PWM Fault input.
A/D input channel 10. Enabled on POR, this analog input overrides
the digital input (read as clear – low level).
LATB<1> data output.
PORTB<1> data input. Weak pull-up available only in this mode.
External interrupt 1 input.
A/D input channel 8. Enabled on POR, this analog input overrides
the digital input (read as clear – low level).
LATB<2> data output.
PORTB<2> data input. Weak pull-up available only in this mode.
External interrupt 2 input.
CAN transmit signal output. The CAN interface overrides the
TRIS<2> control when enabled.
LATB<3> data output.
PORTB<3> data input. Weak pull-up available only in this mode.
CAN receive signal input. Pin must be configured as a digital input by
setting TRISB<3>.
LATB<4> data output.
PORTB<4> data input. Weak pull-up available only in this mode.
Interrupt-on-pin change.
A/D input channel 9. Enabled on POR, this analog input overrides
the digital input (read as clear – low level).
LATB<5> data output.
PORTB<5> data input. Weak pull-up available only in this mode.
Interrupt-on-pin change.
Low-Voltage Programming mode entry (ICSP™). Enabling this func-
tion overrides digital output.
LATB<6> data output.
PORTB<6> data input. Weak pull-up available only in this mode.
Interrupt-on-pin change.
Low-Voltage Programming mode entry (ICSP) clock input.
LATB<7> data output.
PORTB<7> data input. Weak pull-up available only in this mode.
Interrupt-on-pin change.
Low-Voltage Programming mode entry (ICSP) clock output.
Low-Voltage Programming mode entry (ICSP) clock input.
