the current text inherited from the previous pack, or
15 if the current text started before the previous pack.
The 12 payload bytes contain pieces of 0-terminated texts or binary data.
A text may span over several packs. Unused characters in a pack are used for
the next text of the same pack type. If no text of the same type follows,
then the remaining text bytes are set to 0.
The CRC algorithm is known as CRC-16-CCITT with divisor 0x11021.
The CRC algorithm uses divisor 0x11021 and is known as CRC-16-CCITT.
MMC-3 says: "All bits shall be inverted."
The known information about the meaning of the pack payload is incomplete.
Pack types 0x80 to 0x85 and 0x8e contain 0-terminated cleartext.
Type 0x87 seems to contain 2 binary bytes and 10 bytes of 0-terminated
cleartext.
Type 0x8f summarizes the whole list of text packs. (Learned from libcdio.)
The payload bytes of three packs form a 36 byte record.
Byte :
0 : Character code:
0x00 = ISO-8859-1
0x01 = 7 bit ASCII
0x80 = Kanji (japanese)
0x81 = Korean
0x82 = Mandarin (chinese)
0xff = libcdio source states: "everything else"
1 : Number of first track
2 : Number of last track
3 : libcdio source states: "cd-text information copyright byte"
4 - 19 : Pack count of the various types 0x80 to 0x8f.
Byte number N tells the count of packs of type 0x80 + (N - 4).
I.e. the first byte in this field of 16 counts packs of type 0x80.
