The three most significant bits of the command (bit 5 to bit 7) indicates the command type. Bit 0
to bit 4 describes the target address when reading or writing to a control or status register.
Bit 0 to bit 4 in the command Write TX/RX Data Buffer defines the value N (0 N 16). The TX
operation only will be started if the number of bytes in the TX buffer
sure that the datastream will be sent without gaps. The TX operation only will be started if at
least 1 byte are in the TX buffer. This means that N = 0 and N = 1 have the same function.
In all other commands Bit 0 to Bit 4 have no effect and should be set to 0 for compatibility rea-
sons with future products.
