(3) Port alternate switch control register (MUXSEL) (78K0/KA2-L (25, 32-pin products) only)
MUXSEL of 78K0/KA2-L (25-pin and 32-pin products) assigns TOH1, TI51, TI000, and INTP0 pins. By default, TOH1
has no assignment setting.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears MUXSEL to 00H.
