Pin No. SymbolI/OFunction
186DVD-DATA7IDVD parallel compression data from the DVD DSP. When the DVD DSP transmits a 32-bit
187/CDG-SCLKword, it should first describe the WSB.
188DVD-DATA6CDG-SDTA: CD+G (subcode) data, which indicates a serial subcode data input.
189/CDG-SOS1CDG-VSFY: CD+G (subcode) frame sync, which indicates the start of a frame or a
DVD-DATA5composite sync input.
/CDG-VFSYCDG-SOS1: CD+G (subcode) block sync, which indicates a block start sync input.
DVD-DATA4CDG-SCLK: CD+G (subcode) clock, which indicates the input or output of the subcode
/CDG-SDATAdata clock.
190PIO10I/OProgrammable I/O pin, which enters the input mode after resetting.
191VREQUEST OVideo request. The decoder expresses VREQUEST to indicate that the video input buffer
has available space. The polarity is programmable.
192VSTROBEIVideo strobe, which is a programmable, dual-mode pulse and either async or sync. In the
async mode, the external source sends VSTROBE to indicate that it is ready for data
transfer. In the sync mode, the signal becomes the VSTROBE clock data.
193VDD-3.3-3.3 V supply voltage for I/O signals.
194NCONo connection.
195VSS-Core logic and I/O signal grounding.
196V-DACKIVideo data acknowledgement in the case of the sync mode. Expressed when the DVD data
is valid. The polarity is programmable.
197VDD-2.5-2.5 V supply voltage for the core logic.
198RESERVED ICoupled with VSS or VDD-3.3.
199VSS-Core logic and I/O signal grounding.
200ERRORIInput data error. If the ERROR signal from the DSP is unusable, grounding should be performed.
201HOST8SEL IPermanently coupled with VDD-3.3.
202HADDR0Host address bus. This 3-bit address bus selects one of the six hosts interface registers.
203HADDR1I
204HADDR2
205DTACKSEL ICoupled with High to select the WAIT signal or with Low to select the DTACK signal.
(Motorola 68K mode)
206CSIHost chip selection. The host expresses CS to select the decoder for use in read/write.
The read or write operation starts at the negative-going edge of this signal.
207R/WIPerforms strobe read/write in the M mode and strobe write in the I mode. The host expresses
R/W LOW to select write or LOW to select read.
208RDIPerforms strobe read in the I mode. Should be kept HIGH in the M mode.
