signal one block at a time, and one phase at a time. Thus, the address and vector information in block 0 phase A
is sent to the host in packets 1 - 3. Then information in block 0 phase C, two block information words and one long
address, is sent to the host in packets 4-6. Packets 7 - 18 correspond to information in block 1, processed in
phase A first and phase C second.

2, 7 and 11 - 14. The third message is built by relating packets 6 and 15 - 18. Additionally, the host may process
block information in packets 4 and 5 for time setting information.
