Ground
LED driver.
Alternative function: programmable output PIO[30].
LED driver.
Alternative function: programmable output PIO[29].
Reset if low. Pull low for minimum 5ms to cause a
reset.
SPI/PCM select input:
■ 0 = PCM/PIO interface
■ 1 = SPI
Regulator enable input
Can also be sensed as an input.
Regulator enable and multifunction button. A high input
(tolerant to VBAT) enables the on-chip regulators,
which can then be latched on internally and the button
used as a multifunction input
Ground
Charger input.
