FEUL62Q1000 20-4
20.1.3 List of Pins
The I/O pins of the Analog Comparator are assigned to the shared function of the general ports.
For details of pin assignment, see Chapter 17 "GPIO".
Pin name I/O Function
CMPnP I Analog comparator n non-inverting input
CMPnM I Analog comparator n inverting input
(n=0 to 1)
Table 20-2 shows the list of the general ports used for the Analog Comparator and the register settings of the ports.

[Note]
Ÿ
When using the analog comparator, write
"
0
"
to the target PnmIE bit and PnmOE bit of port n mode
registers (n=0 to 9, A, B
，
m=0 to 7) to set the general port to Hi-impedance, otherwise a shoot-through
current may flow.
Ÿ
An influence of the noise is reducible by preventing the switching of neighboring pins while reading the
COMP0D bit when the comparator enables.
