NOTE
The classification is shown in the column labeled “C” in the parameter tables where
appropriate.
3.3
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 Nonvolatile User Options (NVUSRO) register. For a detailed description of the NVUSRO
register, please see the chip reference manual.
3.3.1
NVUSRO[PAD3V5V] field description
Table 12 shows how NVUSRO[PAD3V5V] controls the device configuration.
The DC electrical characteristics are dependent on the PAD3V5V bit value.
3.3.2
NVUSRO[OSCILLATOR_MARGIN] field description
Table 12 shows how NVUSRO[OSCILLATOR_MARGIN] controls the device configuration.
The 4–16 MHz fast external crystal oscillator consumption is dependent on the OSCILLATOR_MARGIN bit value.

Classification tag
Tag description
P
Those parameters are guaranteed during production testing on each individual device.
C
Those parameters are achieved by the design characterization by measuring a statistically
relevant sample size across process variations.
T
Those parameters are achieved by design characterization on a small sample size from typical
devices under typical conditions unless otherwise noted. All values shown in the typical column
are within this category.
D
Those parameters are derived mainly from simulations.
