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.

2.11.1

NVUSRO[PAD3V5V] field description

The DC electrical characteristics are dependent on the PAD3V5V bit value. Table 8 shows how

NVUSRO[PAD3V5V] controls the device configuration.

2.11.2

NVUSRO[OSCILLATOR_MARGIN] field description

The fast external crystal oscillator consumption is dependent on the OSCILLATOR_MARGIN bit value.

Table 9 shows how NVUSRO[OSCILLATOR_MARGIN] controls the device configuration.

2.11.3

NVUSRO[WATCHDOG_EN] field description

The watchdog enable/disable configuration after reset is dependent on the WATCHDOG_EN bit value.

Table 10 shows how NVUSRO[WATCHDOG_EN] controls the device configuration.
