(1)
Voltage input to the GPADC available on the AWR1642.
(2)
Indicates the state of the onboard VIO supply for the AWR device coming from the onboard PMIC. A HIGH on the PGOOD
signal (3.3 V) indicates the supply is stable. Because the I/Os are not failsafe, the MCU must not drive any I/O signals to the
AWR device before this I/O supply is stable to avoid leakage current into the I/Os.
(3)
Controls the onboard PMIC enable. The MCU can use this to shut down the PMIC and AWR device during the periods it does
not use the AWR device and save power. The power up of the PMIC takes approximately 5 ms once the enable signal is made
high.
