The 20-pin debug connector J1 is for interfacing to the CAPTIVATE-PGMR board. This connector provides power, Spy-Bi-Wire, and UART connectivity with the CAPTIVATE-PGMR module.
The Spy-Bi-Wire port lets the user download and debug their own code or the demo code to the MSP430FR2676 MCU on the CAPTIVATE-EMC board.
The MSP430FR2676 MCU communicates with a dedicated USB HID Bridge MCU located on the CAPTIVATE-PGMR module using UART to send sensor data and status to the CapTIvate Design Center as part of the sensor design and tuning process.
