Bits 4 to 6 of the Channel Mode Register enable or disable
Pins 22 to 24 when they are configured as interrupt inputs by
setting Bit 7 of the Channel Mode Register. This function is
controlled for Pins 20 and 21 by Bits 6 and 7 of Configuration
Register 2.
Pins 17 and 18 can be configured as analog inputs or as inputs
for external temperature−sensing diodes by programming Bit 2
of the Channel Mode Register.
Bit 7 of the Channel Mode Register allows the processor
core voltage ID bits (VID0 to VID4, Pins 24 to 20) to be
reconfigured as interrupt inputs.
A truth table for the Channel Mode Register is given in
Table 2.

A−to−D Converter
These inputs are multiplexed into the on−chip, successive
approximation, Analog−to−Digital Converter (ADC). This
has a resolution of eight bits. The basic input range is 0 V to
2.5 V, which is the input range of AIN1 and AIN2, but five
of the inputs have built−in attenuators to allow measurement
of 2.5 V, 5.0 V, 12 V, and the processor core voltages VCCP1
and VCCP2 without any external components. To allow for
the tolerance of these supply voltages, the ADC produces an
output of 3/4 full scale (decimal 192) for the nominal input
