CROLL MAP
The scroll map allows a flexible allocation of data in the memory, to individual rows. Sixteen 12-bit words are provided in
the display memory for this purpose. The bit allocation is shown in Table 67. The scroll map memory is located in the
first 16 words in the display memory (data byte addresses 8000H to 801FH) as shown in Fig.18.
