Description
Adjusts the gain of the voltage channels. +16384 is the typical value. The
gain is directly proportional to the CAL parameter. Allowed range is 0 to
32767. If the gain is 1% slow, CAL should be increased by 1%.
Adjusts the gain of the current channels. +16384 is the typical value. The
gain is directly proportional to the CAL parameter. Allowed range is 0 to
32767. If the gain is 1% slow, CAL should be increased by 1%.
This constant controls the phase compensation. No compensation occurs
when LCOMP2_n =16384. As LCOMP2_n is increased, more compensa-
tion is introduced.
CE codes for CT configuration do not use delay adjustment. These codes
use phase adjustment ( PHADJ_n ).
1.9.2 CALIBRATION MACRO FILE
The macro file in Figure 1-4 contains a sequence of the serial interface commands. It is a simple text file and
can be created with Notepad or an equivalent ASCII editor program. The file is executed with HyperTerminal’s
Transfer->Send Text File command.

Figure 1-4: Typical Calibration Macro File
It is possible to send the calibration macro file to the 71M6543F for “temporary” calibration. This will temporarily
change the CE data values. Upon power up, these values are refreshed back to the default values stored in
flash memory. Thus, until the flash memory is updated, the macro file must be loaded each time the part is
powered up. The macro file is run by sending it with the transfer ? send text file procedure of HyperTerminal.
Use the Transfer ? Send Text File command!
1.9.3 UPDATING THE DEMO CODE (HEX FILE)
The d_merge program updates the hex file (for example 6543eq5_6103_5p3c_01nov10.hex, or similar) with the
values contained in the macro file. This program is executed from a DOS command line window. Executing the
d_merge program with no arguments will display the syntax description. To merge macro.txt and
old_6543_demo.hex into new_6543_demo.hex, use the command:
d_merge old_6543_demo.hex macro.txt new_6543_demo.hex
The new hex file can be written to the 71M6543F/71M6543H through the ICE port using the ADM51 in-circuit
emulator or the TFP-2 flash programmer.
1.9.4 UPDATING CALIBRATION DATA IN FLASH OR EEPROM
It is possible to make data permanent that had been entered temporarily into the CE RAM. The transfer to
EEPROM memory is done using the following serial interface command:
>]CLS
Thus, after transferring calibration data with manual serial interface commands or with a macro file, all that has
to be done is invoking the U command.
