8 Segment Data Buffers
The ePVP6810 chip provides a total of 128 bytes data RAM. On the other hand, display
Segment Data Buffers can be stored either in the data RAM of 128 bytes sizes (00h~40h) or in
the common registers of Bank 2 and Bank 3 (20h~3Fh).
These buffers store display RAM. The display RAM stores the data transmitted from an
external device to the ePVP6810 through the serial interface and is assigned addresses as
follows, in units of 8 bits:
