ATIP decoding function and CRC check function
(decoding/encoding)
CIRC code generation and addition and EFM
modulation (encoding)
CAV audio functions
Provides high-precision CD-R/RW write strategy signal
output
Built-in ATAPI interface (with Ultra DMA 33 support)
Supports 40× decoding and 12× encoding.
Clock frequency: 33.8688 MHz
Transfer rates: Up to 16.6 MB/s (when 32× IORDY
used), up to 33 MB/s when Ultra DMA used. These
values apply when 16-bit 45 ns EDO DRAM is used.
From 1 to 64 Mbits of buffer RAM can be used. (16-bit
data bus EDO DRAM)
The user can freely set up the CD main channel, C2 flag,
and subcode areas in buffer RAM.
Batch transfer function (Function for transferring the CD
main channel, C2 flag, subcode, and other data in a
single operation)
Multi-transfer function (Function for automatically
transferring multiple block to the host in a single
operation)
CAV audio functions
Supports Ultra DMA modes 0, 1, and 2.
