2.1.3 Analog-to-Digital Converter (ADC)
PLAS9-X 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+
.
2.1.4 GPIO Interface
PLAS9-X 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 2.1.5.4), or
may be set as remote host wakeup lines (see Section 2.1.5.3).
