6.0
As with any other register, the I/O register(s) can be
written and read under program control. However, read
instructions (e.g., MOVF PORTB,W) always read the I/O
pins independent of the pin’s Input/Output modes. On
Reset, all I/O ports are defined as input (inputs are at
high-impedance) since the I/O control registers are all
set.
6.1
PORTB is an 8-bit I/O register. Only the low-order 6 bits
are used (RB<5:0>). Bits 7 and 6 are unimplemented
and read as ‘0’s. Please note that RB3 is an input-only
pin. The Configuration Word can set several I/O’s to
alternate functions. When acting as alternate functions,
the pins will read as ‘0’ during a port read. Pins RB0,
RB1, and RB3 can be configured with weak pull-ups
and also for wake-up on change. The wake-up on
change and weak pull-up functions are not pin select-
able. If RB3/MCLR is configured as MCLR, weak pull-
up is always on and wake-up on change for this pin is
not enabled.

Note 1: When MCLREN = 1, the weak pull-up on RB3/MCLR is always enabled.

6.2
The Output Driver Control registers are loaded with
the contents of the W Register by executing the TRIS
f instruction. A ‘1’ from a TRIS Register bit puts the
corresponding output driver in a high-impedance
(Input) mode. A ‘0’ puts the contents of the output data
latch on the selected pins, enabling the output buffer.
The TRIS registers are “write-only” and are set (output
drivers disabled) upon Reset.
Note:
TRIS Registers
If the T0CS bit is set to ‘1’, it will override
the TRIS function on the T0CKI pin.
