After reset: 0000H (output latch) R/W Address:
P9 FFFFF412H,
P9L FFFFF412H, P9H FFFFF413H
Remarks 1. The P9 register can be read or written in 16-bit units.
However, when using the higher 8 bits of the P9 register as the P9H register and the
lower 8 bits as the P9L register, they can be read or written in 8-bit or 1-bit units.
2. To read/write bits 8 to 15 of the P9 register in 8-bit or 1-bit units, specify them as bits
0 to 7 of the P9H register.
