The rule for configuration is that the first byte of the sector is stored at:
BIAH/L(09h/08h,w) - 0Ch
And the following byte is stored into the incremented offset address. If the offset address reaches the
block limit, the next offset address is wrap around to zero. For example, the byte following that at
offset 9FFh is at 000h if block limit is A00h. By this mechanism and following example settings, the
first byte of user data is always located at 000h.
The C2 flag (9FEh), Subcode (980h) and Q-channel (9E0h) data are stored at fixed address if its
associated function is enabled. But the 2352 bytes sector data (including sync, header, user data,
ECC, EDC for Mode 1 sector) can be re-arranged to any other area in the block.
Buffering & Decoding Setting example
The block for buffering and decoding function is set by DDBH/L (29h/28h).
