11.2 Set Page Address (75 H)
This command enters the page address from 0 to 167 to the RAM page register for read/write operations. The driver
supports up to 160 lines. All in all, there are 168 pages. As the addresses are incremented from the start page to the
end page in the page direction scan, the column address is incremented by 1. The page address is then returned to
the start page. Start page < End page must be maintained.
11.3 Set COM Output Scan Direction (BB H)
This command sets the scan direction of the COM output allowing layout flexibility in LCD module assembly. Please
refer to the Table 6 on Page 27 for detail mapping. In addition, the display will have immediate effect once this
command is issued. That is, if this command is sent during normal display, the graphic display will have vertical
flipping effect.
11.4 Set Data Output Scan Direction (BC H)
This command sets the DDRAM such that the MPU operates the display data in the internal RAM.
A. Normal or Inverse page/column/scan directions
