PF9 (PF9H)
(PF9L)
Caution When an output pin is pulled up at EV
DD or higher, be sure to set the PF9n bit to 1.
Remarks 1. The PF9 register can be read or written in 16-bit units.
However, when using the higher 8 bits of the PF9 register as the PF9H register and the
lower 8 bits as the PF9L register, PF9 can be read or written in 8-bit or 1-bit units.
2. To read/write bits 8 to 15 of the PF9 register in 8-bit or 1-bit units, specify them as bits 0
to 7 of the PF9H register.
