Caution Values can only be specified for bits 7 and 0 (OCDENSET and OCDERSD).
When writing, be sure to write 000010B to bits 6 to 1.
Remark The value on bits 3 to 1 will be written over when the on-chip debug function is in use and thus it will become
unstable after the setting.
However, be sure to set the default values (0, 1, and 0) to bits 3 to 1 at setting.
