(PF3L)
Caution When an output pin is pulled up at EVDD or higher, be sure to set the PF3n bit to 1.
Remarks 1. The PF3 register can be read or written in 16-bit units.
However, when using the higher 8 bits of the PF3 register as the PF3H register and the
lower 8 bits as the PF3L register, PF3 can be read or written in 8-bit or 1-bit units.
2. To read/write bits 8 to 15 of the PF3 register in 8-bit or 1-bit units, specify them as bits 0
to 7 of the PF3H register.
