■ P35: The functions of Port 35 are controlled by PFR35 and EPFR35
P35[7:0] is input/output for LCD controller segment driver outputs SEG[7:0], and LIN-UART serial
communication signals SCK, SOT, SIN of channels 8 and 9. Otherwise, the port can be used as general purpose
port.
PFR35.7 0 - Port is in general purpose port mode.
1 - Port is in resource function mode:
Resource function is SEG7 output
PFR35.6 0 - Port is in general purpose port mode.
1 - Port is in resource function mode:
EPFR35.6 0 - Resource function is SEG6 output
