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 4-5 and the falling edge is specified
by the NMI pin edge detection setting, even though a high level is input continuously to the
NMI pin when switching from the NMI pin to the P02 pin (PMC02 bit = 1 → 0), this is
detected as a falling edge as if a high level changed to a low level, and an NMI interrupt
occurs.
To avoid this, set the NMI pin edge detection as “No edge detected” before switching to the
P02 pin.
