During reset input or oscillation stabilization time wait, only the PC contents among the hardwarestatuses become undefined. All other hardware statuses remains unchanged after reset.2. If there is a reset while in the standby mode, the status before reset is maintained even after reset isperformed.3. The values after reset depend on the product.μPD78056F, 78056FY : CCH,μPD78058F, 78058FY : CFH,μPD78P058F, 78P058FY: CFH4. Incorporated only in theμPD78058F, 78058FY, 78P058F, and 78P058FY.
