... CME-12B/BC, such as the D-Bug12 and information from your own programs that send output to the serial port. Also on the disk is a free assembler, example source code, and other tools to get you started. Software Development Software development on the CME12B32 can be performed using either the DBUG12 monitor utility installed in EPROM (sockets U6/U7), the DBUG12 monitor programmed into the internal Flash EPROM or a Background Debug Module (BDM) connected to the BDM-IN connector ...
