General Purpose I/O Functionality
LP5526 has three general purpose I/O pins: GPIO[0]/PWM, GPIO[1] and GPIO[2]. GPIO[0]/PWM can also be
used as a PWM input for the external LED PWM controlling. GPIO bi-directional drivers are operating from the
VDDIO supply domain.
Registers for GPIO are as follows:
