-64CL-M instructions to stop/restart the data link and write data to
the EEPROM.
A function is assigned to each bit of the buffer memory [BFM #27 (1Bh)]. Each function is
executed according to the 0 (OFF)/1 (ON) status of each bit.
Request to write to EEPROM (b4)
When this bit is set to ON, the contents of the detailed remote station information [BFM #32

This write is unnecessary when reserved stations are not specified or when the detailed
remote station information is not edited.
The operation is as shown below.
