WebJun 23, 2024 · A two-byte value is written as four hex digits. Thus $3F represents a byte value and $C008 represents a two-byte value. The first byte of a two-byte value is the most significant byte (MSB). The second byte is the least significant byte (LSB). So given the hex value $C008, the MSB is $C0 and the LSB is $08.
