The following figure illustrates how to connect a user microcontroller DUT to a BM71 EVB to perform the emulation tool function. The pins,
HCI_TXD, HCI_RXD, P2_0, VBAT, RESET, GPIO, and GND, are connected to the DUT. In this
connection, the microcontroller can communicate with the BM71 EVB through the HCI UART interface by a defined command set. The MCU
controls the pin P2_0 and also helps to switch between Application mode and Test
mode.Figure 6-2. UART Connection to Host
