This command reads both vertical and horizontal display start position addresses of GRAM (Refer to sect. 8
- Display Screen and Initialize set on Page # 4). On the parallel interface, the data bus outputs the address
until CSS goes high after the READY signal goes active (Parallel #1:RD=LOW, Parallel #2:R/W=HIGH). The
Data bus becomes an input when other. On the serial interface, TXD outputs the data from SCK rising after
command is issued until the CSS goes high. Refer to 10.Interface on Page #15.
