2.1.3 Digital Audio Interface
ALAS6A-US supports a digital audio interface that can be employed as pulse code modulation
interface. Note that some digital audio interface details are still to be defined, and the feature
scope may be adapted accordingly.
2.1.4 Analog-to-Digital Converter (ADC)
ALAS6A-US 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 0.05V to
V
BATT+
.
2.1.5 GPIO Interface
ALAS6A-US has 10 GPIOs for external hardware devices. Each GPIO can be configured for
use as input or output. All settings are AT command controlled.
GPIO1...GPIO10 may be configured as low current indicator signal (see Section 2.1.6.3), or
may be set as remote host wakeup lines (see Section 2.1.6.4).
