Access Window Read
This command is used to check the set range of the access window.
When the MCU successfully obtains the access window range, the MCU sends the access window start address and end
address that it read. If the SUM of the received command does not match, the MCU sends an error response.
Access window start address LH (1 byte): Start address of the access window range (A15 to A8)

Access window end address LH (1 byte): End address of the access window range (A15 to A8)
Access window end address HL (1 byte): End address of the access window range (A23 to A16)
