than GPIO:
GPIO6/GPIO7: PWM
GPIO8: Pulse Counter/
WD_RETRIG
GPIO20-23: PCM/DAI
VCCref I Vimax = 5.5V
Vimin = 1.8V
Input current has to at least match the
positive output current required by all
configured and used GPIO lines.
For level adjustment.
E.g., connect 5Vout for
5V IO operation.
Must be connected to
1.8...5.5V if employing
signals from GPIO con-
nector.
