modifying the function code parameters.
Besides, EEPROM is stocked frequently, which may shorten the usage time of EEPROM. For
users, some functions are not necessary to be stocked on the communication mode. The needs
can be met on by changing the value in RAM. Changing the high bit of the function code form 0 to 1
can also realize the function. F
Only by changing the value in RAM can set the address to 8007H. This address can only be used
in writing RAM other than reading. If it is used to read, it is an invalid address.
