(1) When running the OOB demo, the RS232 TX and RX pins are used for user and configuration files. This is the same pin connected to
the XDS110 and displayed through the emulator as a Application/User UART COM port.
(2) Controls the PMIC enable for starter kits. The MCU can use this to shut down the PMIC and xWR device during the periods it does not
use the xWR device and save power. The power up of the PMIC takes approximately 5 ms once the enable signal is made high.
2.7.3 60-Pin High Density (HD) Connector (J4 and J17)
The 60-pin HD connector shown in Figure 2-18 provides the high-speed CSI/LVDS data, controls signals (SPI,
UART, I2C, NRST, NERR, and SOPs) and JTAG debug signals from the starter kit. The Trace and DMM
interface lines are also available through this connector.
