(5) Port alternate switch control register (MUXSEL) (78K0/KA2-L (25-pin and 32-pin products) only)
MUXSEL of 78K0/KA2-L (25-pin products) assigns TOH1, TI51, TI000, and INTP0 pins. y default, INTP0 and TI000
are assigned to P00, while TI51 and TOH1 have no assignment setting.
MUXSEL of 78K0/KA2-L (32-pin products) assigns TOH1, TI000, and INTP0 pins. By default, INTP0 and TI000 and
TOH1 have 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.
