Furthermore, the LC89515K SELDRQ pin can be used to perform DRQ (data request) transfers. This is a technique
in which transfers are performed by the host outputting HRD pulses according to a data request signal output from
the LC89515K and is similar to DMA controller operation.
When the last byte of the count specified by the control microprocessor is read, EOP goes active while the read pulse
is output. Also DTEN is set inactive after this time. Next, a transfer complete interrupt is issued to inform the control
microprocessor that the transfer to the host has completed.
The LC89515K control microprocessor can pass the decoding result for the data requested by the host and the CD-
ROM drive status information to the host by writing to the LC89515K internal status registers. The status registers
are a 12-byte FIFO, and the host reads out data while the STEN signal is low. The STEN signal goes high when the
last byte is read. The LC89515K has nothing to do with the content of the status registers.
Since the command and status registers are neither interpreted nor executed by the LC89515K, the LC89515K user
can define the command and status data as unrestricted protocols between the host and the microprocessor. This
allows CD-ROM application systems to be designed without restriction, and also allows an existing system to be
replaced by a system using the LC89515K.
4. Points Common to All Blocks
The LC89515K performs data input and decoding at the same time in a pipelined manner. Also, writes of input data
to the buffer RAM, writes of data to be decoded, and reads to the buffer RAM for transfers to the host all proceed at
the same time with synchronization always being maintained by the LC89515K. Therefore there is no need for the
control microprocessor to be concerned with which master (system block) is accessing the buffer RAM.
