The GPIO’s are controlled via the ITE IT8516F Embedded Controller. Each GPIO has 100pF to ground,
clamping Diode to 3V3 and has multiplexed functionality. Some pins can be DAC (Digital to Analogue
Converter output), PWM (Pulse Width Modulated signal output), ADC (Analogue to Digital Converter input),
TMRI (Timer Counter Input), WUI (Wake Up Input), RI (Ring Indicator Input) or some special function.
