Voice ROM
The VDS84 series embed an 8-bit width voice
ROM for storing sound and tone (melody) data.
Coded data can be saved in an internal mask
ROM by changing one layer of the mask after
the sound and tone (melody) sources are coded
by Holtek's tools. The voice ROM size for
VDS84 series are shown bellow:
