1.10.3 USEFUL CLI COMMANDS INVOLVING THE MPU AND CE
Table 1-12 shows a few essential commands involving MPU data memory.
Command Description
)1=2 Clears the accumulators for Wh, VARh, and VAh by setting bit 1 of the
CONFIG
register.
)A=+2080 Applies the value 208A to the IMAX register
)9=+6000 Applies the value 600V to the VMAX register
)2F?? Displays the total accumulated imported Wh energy
MR2.1 Displays the current RMS voltage in phase A
MR1.2 Displays the current RMS current in phase B
RI5=26
Disables the emulator clock by setting bit 5 in I/O RAM address 0x05. This command will disable
emulator/programmer access to the 71M6534.
RI5=6 Re-enables the emulator clock by clearing bit 5 in I/O RAM address 0x05.
]U
Stores the current CE RAM variables in EEPROM memory. The variables stored in flash memory
will be applied by the MPU at the next reset or power-up if no valid data is available from the
EEPROM.

1.11 USING THE ICE (IN-CIRCUIT EMULATOR)
The ADM51 ICE by Signum Systems ( www.signum.com ) can be used to erase the flash memory, load code
and debug firmware. Before using the ICE, the latest WEMU51 application program should be downloaded from
the Signum website and installed.
It is very important to create a new project and selecting the TERIDIAN 71M6534 IC in the project dialog
when starting a 6534-based design. Using the ICE with project settings copied from a 6521 or 651X de-
signs will lead to erratic results.
For details on installing the WEMU51 program and on creating a project, see the SUG 653X (Software Users’
Guide).
