D0100 (CPU register) 32 words transfer D0064 (EEPROM)
When R0000 is ON, 32 words data starting with D0100 is transferred to D0064 and after in the
EEPROM. (Data write into EEPROM)
Remarks:
•
EEPROM is internally divided by page.
•
Writing data into the EEPROM is available within one page at a time.
•
For data reading from the EEPROM, there is no need to consider the pages.
•
The EEPROM has a life limit for data writing into an address. It is 100,000 times. Pay attention not to
exceed the limit. (EEPROM alarm flag = S0007 is not updated by executing this instruction)
•
Once data writing into the EEPROM is executed, EEPROM access (read/write) is prohibited for the
duration of 10 ms. Therefore, minimum 10 ms interval is necessary for data writing.
