Description
Inductor Pin for BUCK1
BUCK1 feedback pin
GND for internal analog circuit
Charger detection, USB D+
Charger detection, USB D-
Output pin of ALDO1
Output pin of ALDO2
Battery Temperature Sensor Input or an External ADC Input
Output pin of ALDO3
ALDO input source
Internal reference voltage
General purpose I/O or LDO by REG92H. When it's digital input,
the logic high level is 1.5V, and the logic low level is 0.5V
typically. When it's digital output, the logic high level is decided
by REG93H.
General purpose I/O/ADC input or LDO by REG90H. When it's
digital input, the logic high level is 1.5V, and the logic low level
is 0.5V typically. When it's digital output, the logic high level is
decided by REG91H.

GND for internal analog circuit
Power Good pin, push-pull output , and pull to VCC_RTC
internal. COREPWROK is an active high dedicated output signal.
COREPWROK asserts when all voltage rails to the SOC that are
supposed to be on in S0 and S0IX states are within 15% of its
nominal voltage
Clock pin for serial interface, need a 2.2KΩ Pull High.
Data pin for serial interface, need a 2.2KΩ Pull High.
