NVUSRO register
Bit values in the Non-Volatile User Options (NVUSRO) Register control portions of the device configuration, namely electrical
parameters such as high voltage supply and oscillator margin, as well as digital functionality (watchdog enable/disable after
reset).
For a detailed description of the NVUSRO register, please refer to the device reference manual.
4.3.1
NVUSRO[PAD3V5V] field description
The DC electrical characteristics are dependent on the PAD3V5V bit value. Table 7 shows how NVUSRO[PAD3V5V] controls
the device configuration.
4.3.2
NVUSRO[OSCILLATOR_MARGIN] field description
The fast external crystal oscillator consumption is dependent on the OSCILLATOR_MARGIN bit value. Table 8 shows how
NVUSRO[OSCILLATOR_MARGIN] controls the device configuration.
4.3.3
NVUSRO[WATCHDOG_EN] field description
The watchdog enable/disable configuration after reset is dependent on the WATCHDOG_EN bit value. Table 8 shows how
NVUSRO[WATCHDOG_EN] controls the device configuration.
