PIC18F97J60 FAMILY
10.3
PORTB is an 8-bit wide, bidirectional port; it is fully
implemented on all devices. The corresponding Data
Direction register is TRISB. Setting a TRISB bit (= 1)
will make the corresponding PORTB pin an input (i.e.,
put
high-impedance mode). Clearing a TRISB bit (= 0) will
make the corresponding PORTB pin an output (i.e., put
the contents of the output latch on the selected pin). All
pins on PORTB are digital only and tolerate voltages up
to 5.5V.
The Output Latch register (LATB) is also memory
mapped. Read-modify-write operations on the LATB
register read and write the latched output value for
PORTB.
EXAMPLE 10-2:
Each of the PORTB pins has a weak internal pull-up. A
single control bit can turn on all of the pull-ups. This is
performed by clearing bit, RBPU (INTCON2<7>). The
weak pull-up is automatically turned off when the port
pin is configured as an output. The pull-ups are
disabled on all Resets.

Four of the PORTB pins (RB7:RB4) have an
interrupt-on-change feature. Only pins configured as
inputs can cause this interrupt to occur (i.e., any
RB7:RB4 pin configured as an output is excluded from
the interrupt-on-change comparison). The input pins (of
RB7:RB4) are compared with the old value latched on
the last read of PORTB. The “mismatch” outputs of
RB7:RB4 are ORed together to generate the RB Port
Change Interrupt with Flag bit, RBIF (INTCON<0>).

power-managed modes. The user, in the Interrupt
Service Routine, can clear the interrupt in the following
manner:
a)
b)
A mismatch condition will continue to set flag bit, RBIF.
Reading PORTB will end the mismatch condition and
allow flag bit, RBIF, to be cleared.
The interrupt-on-change feature is recommended for
wake-up on key depression operation and operations
where PORTB is only used for the interrupt-on-change
feature. Polling of PORTB is not recommended while
using the interrupt-on-change feature.
For 100-pin devices operating in Extended Micro-
controller mode, RB3 can be configured as the
alternate peripheral pin for the ECCP2 module and
Enhanced PWM output 2A by clearing the CCP2MX
Configuration bit. If the devices are in Microcontroller
mode, the alternate assignment for ECCP2 is RE7. As
with other ECCP2 configurations, the user must ensure
that the TRISB<3> bit is set appropriately for the
intended operation.
Any read or write of PORTB (except with the
MOVFF (ANY), PORTB instruction). This will
end the mismatch condition.
