Note 1: These parameters are not characterized or tested in manufacturing.
2: With no missing codes.
3: These parameters are characterized, but not tested in manufacturing.
4: Characterized with a 1 kHz sine wave.
5: Overall functional device operation at V
BORMIN < VDD < VDDMIN is tested, but not characterized. All device
Analog modules, such as ADC, etc., will function, but with degraded performance below V
DDMIN. Refer to
parameter BO10 in Table 30-10 for V
BORMIN values.
