AWR1642 Evaluation Module (AWR1642BOOST) Single-Chip mmWave
Sensing Solution
(1)
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.
