PGOOD – This signal indicates that 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 ensure that it does 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.

CAN Interface Connector (for AWR1443)
The J3 connector provides the CAN_L and CAN_H signals (see
transceiver (SN65HVDA540). These signals can be directly wired to the CAN bus.
Because the digital CAN signals (TX and RX) are muxed with the SPI signals on the AWR device, one of
the two paths must be selected. To enable the CAN interface, the R11 and R12 resisters muct be
populated with 0 Ω, and the R4, R6, R28, and R63 resisters must be removed to disconnect the SPI path.
