59 / 103 page ![]() SPC560P34L1, SPC560P34L3, SPC560P40L1, SPC560P40L3 Electrical characteristics Doc ID 16100 Rev 7 59/103 Figure 13. Brown-out typical sequence 3.10 DC electrical characteristics 3.10.1 NVUSRO register Portions of the device configuration, such as high voltage supply and watchdog enable/disable after reset are controlled via bit values in the non-volatile user options (NVUSRO) register. For a detailed description of the NVUSRO register, please refer to the device reference manual. NVUSRO[PAD3V5V] field description The DC electrical characteristics are dependent on the PAD3V5V bit value. Table 18 shows how NVUSRO[PAD3V5V] controls the device configuration.
