VDBTH is set to a default value of 3.10 V during the internal power-on-reset cycle. It may then be changed by data in the EEPROM.
Debounce interval is measured from the last bounce detected.
Based on 32.768 KHz crystal frequency
VIN, VIN[0], VIN[2], VIN[4], VIN[7], VIN[31], VIN[65] must be at the same voltage
Electrical Parameters – LDO Regulators
VIN = 3.0 V – 5.5 V, TA = – 20°C to 85°C unless otherwise noted. Typical values are at TA = +25°C and VIN = 3.6V. COUT = 0.47 µF unless otherwise specified.
