For example, the address of F00.14 is 000EH (00D=00H, 14D=0EH).
Function code (not saved after power-down) 8000H-EF63H When the parameters are set with the function code 0x06 or 0x10, the function that “the settings are valid immediately and not saved after power-down” can be realized in the form of “original address +8000H”. For example, the corresponding address of F00.14 is 800EH (=000EH+8000H).
