WDT counter: When WDTEN is enabled with the SAFE command, you must periodically enter the WDTCL command from the master side. If WDTCL is not entered on a regular basis, you can determine that there is a problem with the master.
RST counter: When RSTEN is enabled with the SAFE command, the count-up starts when an erroneous operation is detected or a failure is detected, and the count-up is stopped by inputting ERRCL within the specified time. If it overflows, the operation shifts to the state set by Speech LSI Utility.
