5.0 APPLICATION INFORMATION

5.1 Host MCU Interface

The BM62/64 module supports UART commands. The

UART commands enable an external MCU to control

the BM62/64 module. Figure 5-1 illustrates the UART

interface between the BM62/64 module and an

external MCU.

FIGURE 5-1: HOST MCU INTERFACE OVER UART

An external MCU can control the BM62/64 module over

the UART interface and wakeup the module with the

MFB, P0_0 (BM62) and P3_7 (BM64) pins.

Refer to the “UART_CommandSet” document for a list

of functions the BM62/64 module supports and how to

use the UI tool to configure the UART and UART Com-

mand Set tool.

Note: The UART Command set tool (SPKCom-

mandSetTool v160.xx) and “UART_Com-

mandSet” document are available for
