Note
When reading from or writing to bits 8 to 15 of the PMC9 register in 8-bit or 1-bit units,
specify these bits as bits 0 to 7 of the PMC9H register.
Remark
The PMC9 register can be read or written in 16-bit units.
However, when the higher 8 bits and the lower 8 bits of the PMC9 register are used
as the PMC9H register and as the PMC9L register, respectively, these registers can
be read or written in 8-bit or 1-bit units.
