PID Registers (0x400 ~ 0x47e)

These registers should be written with certain

values during initialization phase, because the

values are undefined at first. Video, audio, and

auxiliary packet will be respectively transferred to

VAD_DATA port with VID_STRB, AUD_STRB,

and DATA_STRB signal in case Hig bit in the

priority. This is equally applied to other packets.).

Other data will be transferred to the corresponding

buffer in DRAM.

Vid PID Register (0x400, 0x402)

These registers should be written with certain

values during initialization phase, because the

values are undefined at first. For correct processing,

Dst should be written to ‘0’.
