External Configuration and

Programming

The BM62/64 module can be configured using an

external configuration tool (EEPROM tool) and firm-

ware is programmed using a programming tool (Flash

tool).

Figure 5-10 illustrates the configuration and firmware

programming interface on the BM62 module. It is

recommended to include a header pin on the main PCB

for development.

FIGURE 5-10:

EXTERNAL PROGRAMMING HEADER CONNECTIONS

Configuration and firmware programming modes are

entered according to the system configuration I/O pins.

Table 5-1 provides the system configuration settings.

The P2_0, P2_4 and EAN pins have internal pull up.

Note:

The EEPROM tool and Flash tool are

available for download from the Microchip

web site at: www.microchip.com/BM62
