Byte Constant
Value (1 byte, valid
range: 0x00 - 0xFF)
When receiving a message with a constant, the
received value will be checked against this value.
If the values differ, the message will be ignored
(little endian).

range: 0x0000 -
0xFFFF)
When receiving a message with a constant, the
received value will be checked against this value.
