The internal RAM contains display and row control registers. The display registers have 240 locations
that are allocated between row 0/column 0 and row 9/column 23, as shown in Figure 5. Each display
register has a blink bit, and its corresponding character address on the ADDRESS byte and 2 color
selection bits on the ATTRIBUTE bytes. The row control register is allocated between columns 28 and
31 for rows 0 to 9; it is used to set character size and color attribute for each respective row. If double
width character is chosen, only even column characters may be displayed on-screen and the odd
column characters will be hidden.
