In Section 9.1 “PORTA, TRISA and LATA Regis-
ters”, the sixth paragraph and its associated note
(see below) have been removed.
Pins RA0 through RA5 may also be used as com-
parator inputs or outputs by setting the appropriate
bits in the CMCON register. To use RA3:RA0 as
digital inputs, it is also necessary to turn off the
comparators.
In Section 22.3 “LCD Bias Types”, the third para-
graph has been modified (changes are shown in
bold text) to read as follows.
The external resistor ladder should be connected
to the Bias 1 pin, Bias 2 pin, Bias 3 pin and V
The Bias 3 pin should also be connected to AV
DC Characteristics:
The power-down current in Sleep mode does not depend on the oscillator type. Power-down current is
measured with the part in Sleep mode, with all I/O pins in high-impedance state and tied to V
features that add delta current disabled (such as WDT, Timer1 Oscillator, BOR, etc.).
On a Power-on Reset, RA5 and RA3:RA0
are configured as analog inputs and read
as ‘0’. RA4 is configured as a digital input.
