File Operation
Since the AT381x settings are stored in the file, after the Modbus command is set, the data
cannot be stored in the internal FlashRom in real time, which will cause the register data
before the next power-on to be restored to the original file value.
Users can store all set values in the current or specified file with the file manipulation registers.
Meanwhile, the specified file data can also be recalled into the setup register.
12.5.1
Save to Current File [4000H]
Send a value of 0001 to 4000 registers, the AT381x will perform a file write operation, and all
settings will be saved to the current file.
This register cannot be read.
