DVD parallel compression data from the DVD DSP. When the DVD DSP transmits a 32-bit
word, it should first describe the WSB.
CDG-SDTA: CD+G (subcode) data, which indicates a serial subcode data input.
CDG-VSFY: CD+G (subcode) frame sync, which indicates the start of a frame or a
composite sync input.
CDG-SOS1: CD+G (subcode) block sync, which indicates a block start sync input.
CDG-SCLK: CD+G (subcode) clock, which indicates the input or output of the subcode
data clock.
Programmable I/O pin, which enters the input mode after resetting.
Video request. The decoder expresses VREQUEST to indicate that the video input buffer
has available space. The polarity is programmable.
Video 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.
3.3 V supply voltage for I/O signals.
No connection.
Core logic and I/O signal grounding.
Video data acknowledgement in the case of the sync mode. Expressed when the DVD data
is valid. The polarity is programmable.
2.5 V supply voltage for the core logic.
Coupled with VSS or VDD-3.3.
Core logic and I/O signal grounding.
Input data error. If the ERROR signal from the DSP is unusable, grounding should be performed.
Permanently coupled with VDD-3.3.
Host address bus. This 3-bit address bus selects one of the six hosts interface registers.
Coupled with High to select the WAIT signal or with Low to select the DTACK signal.
(Motorola 68K mode)
Host 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.
Performs 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.
Performs strobe read in the I mode. Should be kept HIGH in the M mode.
Pin No.
