Remark
Remark
(2) In port mode, the PFn.PFnm bit is valid only in the output mode (PMn.PMnm bit = 0). In the input mode (PMnm bit
= 1), the value of the PFnm bit is not reflected in the buffer.

NMI interrupt occurrence
NMI interrupt occurrence
When the P02/NMI pin is pulled up as shown in Figure 4-34 and the falling edge is specified in
the NMI pin edge detection setting, even though high level is input continuously to the NMI pin at
switching from the NMI pin to the P02 pin (PMC02 bit = 1 → 0), this is detected as falling edge
as if high level changed to low level, and NMI interrupt occurs.
To avoid this, set the NMI pin edge detection as “No edge detected” before switching to the P02
pin.
