Preliminary/Confidential
ATAPI CD-ROM Decoder & Controller
This specification is subject to change without notice.
Publication Release Date: Aug, 1996
Preliminary/ Confidential Revision A0.1
- 35 -
DTEN (01h.1)
1
Loading the number of bytes/words minus 1 to TBCL and TBCH
UDTS (1Fh.6)
1
Writing registers DF0-7
Writing any value to register THTRG (06h)
Set UDTT (1Fh.7) high
Set UDTT (1Fh.7) low
The end of data transfer can be monitored by TENDb (01h.6). The corresponding interrupt can be
cleared by writing any value to TACK (07h) if TENDEN (01h.6) is enabled. However, DFRDYb
(01h.1) is meaningless because DATA FIFO is not used. Register TACL (04h) and TACH (05h)
are useless in this case.
Bit 5: H16S - Host 16-bit Data Select
To abide by ATAPI protocol, this bit should be high to select 16-bit data transfer between
W88111AF/W88112F and host.
Bit 4: LAEN - Latch Enable
If this bit is high, host address and chip-select signals will be latched when pins HRDb or HWRb
change from high to low.
Bit 3: MDMA - Multi-word DMA mode
Setting this bit high enables multi-word DMA mode if PIO (1Fh.2) is low.
Bit 2: PIO - PIO/DMA mode select
Setting this bit high causes data transfer to/from host using PIO mode.
Bit 1: WDMA - Host write DMA mode
Setting this bit high select data transfer direction of DMA is from host to device.
Bit 0: Defined 0
STAT5 - Status Register 5 - (read 1Fh)
Bit 7: UTBY - Microprocessor to RAM Transfer Busy
When the microprocessor-to-RAM transfer is not complete, this bit is high.
