When peripheral functions are multiplexed onto general I/O pins, the functionality of the I/O pins
may change to accommodate the requirements of the peripheral module. Examples of this are
the Analog-to-Digital (A/D) converter and LCD driver modules, which force the I/O pin to the
peripheral function when the device is reset. In the case of the A/D, this prevents the device from
consuming excess current if any analog levels were on the A/D pins after a reset occurred.
With some peripherals, the TRIS bit is overridden while the peripheral is enabled. Therefore,
read-modify-write instructions (BSF, BCF, XORWF) with TRIS as destination should be avoided.
The user should refer to the corresponding peripheral section for the correct TRIS bit settings.
PORT pins may be multiplexed with analog inputs and analog V
of these pins is selected, to be an analog input or digital I/O, by clearing/setting the control bits
in the ADCON1 register (A/D Control Register1). When selected as an analog input, these pins
will read as ‘0’s.
The TRIS registers control the direction of the port pins, even when they are being used as ana-
log inputs. The user must ensure the TRIS bits are maintained set when using the pins as analog
inputs.

pins are configured as LCD driver segments, as controlled by the LCDSE register.
To configure the pins as a digital port, the corresponding bits in the LCDSE register
must be cleared. Any bit set in the LCDSE register overrides any bit settings in the
corresponding TRIS register.

PORTE. The microprocessor port becomes enabled when the PSPMODE bit is set.
In this mode, the user must make sure that the TRISE bits are set (pins are config-
ured as digital inputs) and that PORTE is configured for digital I/O. PORTD will over-
ride the values in the TRISD register. In this mode the PORTD and PORTE input
buffers are TTL. The control bits for the PSP operation are located in TRISE.
