The 60-pin HD connector provides high speed data over CSI or the HS_DEBUG interface, and controls signals (SPI, UART, I2C, NRST, NERR, and SOPs) and JTAG debug signals (see Table 2-3). This connector can be connected to the MMWAVE-DEVPACK board and interface with the TSW1400 (see Figure 2-7).

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.
