PIN DESCRIPTION

Pins are sorted by functional groups.

The power domain associated with each pin is noted; VPMIC is the domain powered by LDO12 for the ‘always-on’

functions internal to the WM8311.

Note that an external level-shifter may be required when interfacing between different power domains.
