3.5 Pulse Code Modulation Interface (PCM)
ALS6A-E's PCM interface can be used to connect audio devices capable of pulse code modu-
lation. The PCM functionality is limited to the use of wideband codecs with 16kHz sample rate
only.
3.6 Analog-to-Digital Converter (ADC)
ALS6A-E provides two unbalanced ADC input lines: ADC1_IN and ADC2_IN. They can be
used to measure two independent, externally connected DC voltages in the range of 0.3V to
3.075V. They can also be used for antenna diagnosing.
3.7 GPIO Interface
ALS6A-E has 10 GPIOs for external hardware devices. Each GPIO can be configured for use
as input or output. All settings are AT command controlled.
