5.5.CE/MPU INTERFACE
The interface between the CE and the MPU is described completely in the 71M6511 and 71M6513 Data Sheets.
5.6.SOURCE FILES
The functionality of the Demo Code is implemented in the following files and directories:
1.
CLI:
Command Line Interface – General Commands
access.c
SFR, I/O RAM, MPU and CE data access
cli.c
parser for command line interface
cmd_ce.c
sub-parser for CE commands
cmd_misc.c
sub-parser for RTC, EEPROM, trim and PS commands
io.c
number conversion functions and auxiliary routines for CLI
load.c
upload and download
sfrs.c
access to SFRs
When compiled, CLI.C takes about 20Kbytes of program space. When designing a real meter, CLI.C can
easily be removed without major changes to the software.
