3.Port Register Settings
■ P34: The functions of Port 34 are controlled by PFR34 and EPFR34
P34[7:0] is input/output for LCD controller segment driver outputs SEG[15:8], and LIN-UART serial
communication signals SCK, SOT, SIN of channels 10 and 11. Otherwise, the port can be used as general
purpose port.
PFR34.7 0 - Port is in general purpose port mode.
1 - Port is in resource function mode:
