Electrical characteristics
Table 4. PAD3V5V field description1
Value2
Description
0
High voltage supply is 5.0 V
1
High voltage supply is 3.3 V
1 See the device reference manual for more information on the NVUSRO register.
2 '1' is delivery value. It is part of shadow Flash, thus programmable by customer.
The DC electrical characteristics are dependent on the PAD3V5V bit value.
3.2.2 NVUSRO[OSCILLATOR_MARGIN] field description
Table 5 shows how NVUSRO[OSCILLATOR_MARGIN] controls the device configuration.
Table 5. OSCILLATOR_MARGIN field description1
Value2
Description
0
Low consumption configuration (4 MHz/8 MHz)
1
High margin configuration (4 MHz/16 MHz)
1 See the device reference manual for more information on the NVUSRO register.
2 '1' is delivery value. It is part of shadow Flash, thus programmable by customer.
The main external crystal oscillator consumption is dependent on the OSCILLATOR_MARGIN bit value.
3.2.3 NVUSRO[WATCHDOG_EN] field description
Table 5 shows how NVUSRO[WATCHDOG_EN] controls the device configuration.
Table 6. WATCHDOG_EN field description1
Value2
Description
0
Disable after reset
1
Enable after reset
1 See the device reference manual for more information on the NVUSRO register.
2 '1' is delivery value. It is part of shadow Flash, thus programmable by customer.
