Section 9 Peripheral I/O Mapping Controller
The peripheral function mapping controller (PMC) is composed of registers that are used to select
the functions of multiplexed pins. The multiplexed pins are divided into two groups: group 1 and
group 2. Group 1 consists of ports 1 to 3, 5, and 6, and group 2 consists of ports 8, 9*, and A.
Tables 9.1 and 9.2 list the functions of the multiplexed pins in each group.
Note: Port 9 is not available on the H8S/20103 and H8S/20115 Groups.

Notes: 1. The timer RC is not available on the H8S/20203, H8S/20223, H8S/20215, and
H8S/20235 Groups; therefore, the function cannot be selected for these groups.
2. The SCL and SDA functions for the IIC2 module are not allocatable to pins other than
P56 and P57.
