Electrical characteristics
Doc ID 14619 Rev 4
4.3
NVUSRO register
Portions of the device configuration, such as high voltage supply, oscillator margin, and
watchdog enable/disable after reset are controlled via bit values in the Non-Volatile User
Options Register (NVUSRO) register.
4.3.1
NVUSRO[PAD3V5V] field description
Table 5 shows how NVUSRO[PAD3V5V] controls the device configuration.
The DC electrical characteristics are dependent on the PAD3V5V bit value.
4.3.2
NVUSRO[OSCILLATOR_MARGIN] field description
Table 6 shows how NVUSRO[OSCILLATOR_MARGIN] controls the device configuration.
The fast external crystal oscillator consumption is dependent on the
OSCILLATOR_MARGIN bit value.
