Notes: 1. The timer RC is not available on the H8S/20203, H8S/20223, H8S/20215, and
H8S/20235 Groups. These bits are reserved and the function cannot be selected for
these groups.
2. This function cannot be selected for the H8S/20103 and H8S/20115 Groups.
3. If the NMOS open-drain output is selected for the SSCK output pin or the SSO output
pin, use the PMC to allocate that pin from port 5.
