DC electrical characteristics

3.10.1

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 (NVUSRO) register.

For a detailed description of the NVUSRO register, please refer to the device reference manual.

3.10.1.1

NVUSRO[PAD3V5V] field description

The DC electrical characteristics are dependent on the PAD3V5V bit value. Table 15 shows how NVUSRO[PAD3V5V]

controls the device configuration.

3.10.1.2

NVUSRO[OSCILLATOR_MARGIN] field description

The fast external crystal oscillator consumption is dependent on the OSCILLATOR_MARGIN bit value. Table 16 shows how

NVUSRO[OSCILLATOR_MARGIN] controls the device configuration.

3.10.2

DC electrical characteristics (5 V)

Table 17 gives the DC electrical characteristics at 5 V (4.5 V < VDD_HV_IOx < 5.5 V, NVUSRO[PAD3V5V] = 0).

Table 15. PAD3V5V field description

Value1

1 Default manufacturing value before flash initialization is ‘1’ (3.3 V).

Description

High voltage supply is 5.0 V

High voltage supply is 3.3 V

Table 16. OSCILLATOR_MARGIN field description

Value1

1 Default manufacturing value before flash initialization is ‘1’.

Description

Low consumption configuration (4 MHz/8 MHz)

High margin configuration (4 MHz/16 MHz)
