Portions of the MPC5604P device configuration, i.e., high voltage supply, oscillator margin, and watchdog enable/disable after
reset) are controlled via bit values in the NVUSRO register. NVUSRO[PAD3V5V] controls the device configuration as follows:
The DC electrical characteristics in the following sections are dependent on the PAD3V5V value as described above.
