Section 2 Port Functions
Note
If PIPCn.PIPCn_m = 1, the I/O direction is directly controlled by the alternative
function and PM is ignored.
Pins that have multiple functions multiplexed with a control mode (ALT-IN) and
pins allocated to multiple port pins (excluding ESO2/INTP8) are listed in the
following table.
Caution 1.
Do not use alternative function pins simultaneously (for example,
ADCA0TRG0 and INTP3). However, edges for the INTP pins are detectable as
the edges on the URTH0RXD, and URTH1RXD pins, respectively, in the case
of the multiplexed pins for URTH0RXD/INTP0 and URTH1RXD/INTP1.
Caution 2. Do not use the same alternative function pin with multiple port pins (For
example, if ADCA0TRG0/INTP3 is in use, ALT_IN1 of P0_2, ALT_IN4 of P5_1,
and so on).
