RX23W Group 22. Multi-Function Pin Controller (MPC)
22. Multi-Function Pin Controller (MPC)
22.1 Overview
The multi-function pin controller (MPC) is used to allocate input and output signals for peripheral modules and input
interrupt signals to pins from among multiple ports.
Table 22.1 shows the allocation of pin functions to multiple pins. The symbols and × in the table indicate whether the
pins are or are not present on the given package. Allocating the same function to more than one pin is prohibited.
