3. To switch to external interrupt input (INTPn) from the port mode (by changing the
1 and then specify the edge to be detected and enable the operation of A/D converter
0 or 1 because the trigger may be input if a wrong valid edge is detected (n = 4, 5).
PMC0.PMC0n bit from 0 to 1), an external interrupt may be input if a wrong valid edge
is detected. Therefore, be sure to disable edge detection (INTF0.INTF0n bit = 0 and
INTR0.INTR0n bit = 0), select external interrupt input (INTPn), and then specify the
valid edge (n = 0 to 7).
When switching to the port mode from external interrupt input (INTPn) (PMC0n bit = 1
→ 0), an edge may be detected. Be sure to disable edge detection (INTF0n bit = 0,
INTR0n bit = 0), and then select the port mode.
