CHAPTER 4 PORT FUNCTIONS
Cautions 3. To switch to external interrupt input (INTP0n) from the port mode (by changing the
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 (INTP0n), and then specify the
valid edge (V850E/IF3: n = 0, 1, V850E/IG3: n = 0 to 7).
When switching to the port mode from external interrupt input (INTP0n) (by changing
the PMC0n bit from 1 to 0), an edge may be detected. Therefore, be sure to disable
edge detection (INTF0n bit = 0, INTR0n bit = 0), and then select the port mode.
4. To control high-impedance output of the external interrupt function and motor output
control function, set the PMC0n bit to 1 (V850E/IF3: n = 0, 1, V850E/IG3: n = 0 to 7).
