P9 (P9H)
(P9L)
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, P9 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.

(PM9L)
Remarks 1. The PM9 register can be read or written in 16-bit units.
However, when using the higher 8 bits of the PM9 register as the PM9H register and the
lower 8 bits as the PM9L register, PM9 can be read or written in 8-bit and 1-bit units.
2. To read/write bits 8 to 15 of the PM9 register in 8-bit or 1-bit units, specify them as bits 0 to 7
of the PM9H register.
