Connection Example (Host Interface in HCI Mode)

The UART interface can be connected with a UART interface on a host CPU.

Figure 4-3 shows an example of the connection with an external host CPU for the 2-wire start-stop synchronization data transfer

(Reception data and Transmission data). When the HCI mode is selected, the built-in firmware assigns the UART function to the

corresponding GPIO pins. Figure 4-4 shows the timing of the assignment when the UART function is assigned to the GPIO pins in

the HCI mode.
