value for all bits in the register and click the OK
button. This will set all bits at once. The new value
will be reflected in the pattern of checks in the reg-
ister check boxes and immediately downloaded to
either the CS4954/55 or the FPGA.
2.2.2
If you use the CDB4954A/55A Evaluation Board
with a PC, the Action Menu will allow you to con-
vert bitmaps of up to 720x480 pixels to CCIR656
PAL or NTSC files. These converted files can then

be downloaded to the FLASH on the evaluation
board for storage and later replay, or downloaded
directly to SDRAM for immediate playing.
2.2.2.1
This option converts a bitmap image (“.bmp” file
extension) of up to 720x480 into a CCIR656 NTSC
(“.nts” file extension) or PAL (“.pal” file exten-
sion) file. This step is necessary before attempting
to download either a NTSC or PAL image to
SDRAM and displaying it. It is also necessary be-
fore saving an NTSC or PAL file to FLASH.
