OPINSEL is an 8-bit readable/writable register that selects whether or not output signals
(EXDTCEN, EXMSTP, EXMSN) to externally connected modules are output to pins P77 to P74
in H8S/2214 Group operation. OPINSEL bits 6 to 4 are initialized to 000 by a power-on reset and
in hardware standby mode. They retain their previous states in a manual reset and in software
standby mode.
