Caution Be sure to set bits 15 to 10, 7, and 6 to “0”.
Remarks 1. The PMC3 register can be read or written in 16-bit units.
However, when using the higher 8 bits of the PMC3 register as the PMC3H register and
the lower 8 bits as the PMC3L register, PMC3 can be read or written in 8-bit or 1-bit units.
2. To read/write bits 8 to 15 of the PMC3 register in 8-bit or 1-bit units, specify them as bits
0 to 7 of the PMC3H register.
