The debugger is not initialized in software standby mode. However, since this LSI's internal
operation halts in software standby mode:
1. When AUDMD is high (RAM monitor mode), Ready is not returned (Not Ready continues to
2. When AUDMD is low (branch trace mode), operation stops. However, operation continues
