The answer of the MSI 430 module is listed in the following table. The first byte of the type ID is 0x9a =
0b1001 1010, meaning that the data type is given in the following byte and the data size in the byte after
that. The fourth byte of the type ID is 0x42 = 0b0100 0010, standing for an integer data type of size 2.
