[19:14] Bit alignment of the CRC register is according to
their incoming order. The first incoming bit
becomes LSB, i.e. CRC [19:14] = {b19, b18, b17,
b16, b15, b14}, where bn represents data bit with
their incoming order n.
The CRC used is X^6+ X + 1, all preset to 1.
[13:6] Bit alignment of the Word 2 register is according to
their incoming order. The first incoming bit
becomes LSB, i.e. Word 2 [13:6] = {b13, b12, b11,
b10, b9, b8, b7, b6}, where bn represents data bit
with their incoming order n.
The Word 2 data are used for copy control:
b7, b6 :
00 copying permitted
01 one copy permitted
10 reserved
11 no copying permitted
b9 b8 :
(reserved)
b10 :
0 not analog pre-recorded medium
1 analog pre-recorded medium
b13, b12, b11 :
(reserved)
[5:2] Bit alignment of the Word 1 register is according to
their incoming order. The first incoming bit
becomes LSB, i.e. Word 1 [5:2] = {b5, b4, b3, b2},
where bn represents data bit with their incoming
order n.
The Word 1 data are used to indicate the existence
of Word 2 data:
b5, b4, b3, b2 :
