Chapter 30 I/O Ports
3.Port Register Settings
■ P32: The functions of Port 32 are controlled by PFR32 and EPFR32
P32[7:0] is input/output for LCD controller segment driver outputs SEG[31:24], and LIN-UART serial
communication signals SCK, SOT, SIN of channels 14 and 15. Otherwise, the port can be used as general
purpose port.
PFR32.7 0 - Port is in general purpose port mode.
