The 26 bits of transmission consists of two parity bits and 24 code bits.
The 8 first code bits are encoding the facility code. This code identifies
each MorphoAccess™ in a network.
The 16 other bits are data bits.
The first bit transmitted is the first parity bit. It is even parity calculated
over the first 12 bits.
The last bit transmitted is the second parity bit. It is odd parity bit
calculated over the last 12 code bits.
