11.7. Things to Do after Replacing IC or X'tal

If repairing or replacing BBIC (FLASH type), EEPROM and X'tal, it is necessary to download the required data such as
Programming data or adjustment data, etc in memory.
The set doesn't operate if it is not executed.

11.7.1. How to download the data

11.7.1.1. Base Unit
First, operate the PC setting according to The Setting Method of JIG (Base Unit)(P.54).
Then download the appropriate data according to the following procedures.
EEPROM (IC611)
X'tal (X501)
Note:
(*1)WW: Destination code XXX_YYY: revision number
'WW', "XXX_YYY" vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in The Setting
Method of JIG (Base Unit) (P.54).
(*2) Refer to Check Point (Base Unit) (P.41)
Items
Adjusted parameter data is stored in memory.
(country version batch file, default batch file,
etc.)
System clock
How to download/Required adjustment
1) Change the address "0001" of EEPROM to "55" to download
the data.
2) Default batch file: Execute the command "default.bat".
3) Country version batch file: Execute the command
"TG6721EU_WW_RevXXX_YYY.bat" (*1)
4) Clock adjustment: Refer to Check Point (E). (*2)
Clock adjustment data is in EEPROM, adjust the data again
after replacing it.
1) Apply 5.5V between DCP ad DCM with DC power.
2) Input Command "sendchar sfr", then you can confirm the cur-
rent value.
3) Check X'tal Frequency.(13.824 MHz ± 100 Hz).
4) If the frequency is not 13.824 MHz ± 100 Hz, adjust the fre-
quency of CKM executing the command "sendchar sfr xx xx
(where xx is the value)" so that the reding of the frequency
counter is 13.824000 MHz ± 7 Hz.
