• Description: SuperH RISC engine
• Manufacturer: Hitachi Semiconductor

14.1
The pin function controller (PFC) is composed of registers for selecting the function of
multiplexed pins and the direction of input/output. The pin function and input/output direction can
be selected for each pin individually without regard to the operating mode of the LSI. Table 14.1
lists the multiplexed pins.
