Description
Reserved (Read Only). Reads back as 0.
Gamma Address. Specifies the address to be used for the next access to the Palette
Data register (VP Memory Offset 040h[23:0]). Each access to the PDR automatically
increments the PAR. If non-sequential access is made to the palette, the PAR must be
loaded between each non-sequential data block.
Description
Reserved (Read Only). Reads back as 0.
Palette Data. Contains the read or write data for a Gamma Correction RAM (palette).
Provides the video palette data. The data can be read or written to the Gamma Correc-
tion RAM (palette) via this register. Prior to accessing this register, an appropriate
address should be loaded to the PAR (VP Memory Offset 038h[7:0]). Subsequent
accesses to the PDR cause the internal address counter to be incremented for the next
cycle.
Note:
When a read or write to the Gamma Correction RAM occurs, the previous output
value is held for one additional DOTCLK period. This effect should go unnoticed
during normal operation.
