1.1.4 Data

For read commands, one byte is used. This number represents the number of bytes to read - 1, with a maximum of 128 bytes requested, for example: 0x00 to read one byte of data.

For write commands, this represents the data bytes to be written, with a maximum of eight bytes of data to send, for example: 0xA500 to write two bytes with data 0xA500.
