These buffers store display RAM. The display RAM stores the data transmitted from an external
device to the ePVP6300 through the serial interface and is assigned addresses as follows, in units
of 8 bits:
b0
b3 b4
b7
X X HL
X X HU
Lower 4 bits
Higher 4 bits
Only the lower 4 bits of the addresses assigned to SEG17 through SEG20 are valid and the
higher 4 bits are ignored.
