In ANALOG mode, P31 and P32 have a comparator front end. The comparator reference
is supplied by P33 and P
ing IRQ1 are diverted to the Stop Mode Recovery sources (excluding P31, P32, and P33)
as displayed in
input register, which then generates IRQ1.
Comparators are powered down by entering STOP mode. For P30:P33 to be used as a
Stop Mode Recovery source, these inputs must be placed into DIGITAL mode.
The comparators can be programmed to be output on P34 and P37 by setting bit 0 of the
PCON Register.
The Port Configuration (PCON) register
the comparator output on Port 3. The PCON register is located in expanded register Bank
F, address 00h.
