Note: 1. With the output Nch transistor off in shared I/O ports with the open-drain output specifications. These pins cannot be used as input pins if the
CMOS output specifications are selected.
2. With the output Nch transistor off in shared I/O ports with the open-drain output specifications. The rating for the pull-up output specification pins is
stipulated in terms of the output pull-up current IPO. These pins cannot be used as input pins if the CMOS output specifications are selected.
3. With the output Nch transistor off for CMOS output specification pins. (Also applicable when the p-channel open-drain option is specified for P8.)
4. With the output Nch transistor off for pull-up output specification pins.
5. Applies to P8 when the CMOS output specifications are selected.
6. With the output Nch transistor off for open-drain output specification pins.
7. With the output Pch transistor off for open-drain output specification pins.
