Q01. How do I treat the CS# signal in burst mode?
A.In burst mode, the automatic address increment in effect is independent of whether the CS# is set to H each time or kept to L.
Q02. Is block write possible in burst mode?
A.Block writes are possible since the data in the area set at the start/end positions are updated.
Q03. Please provide the timings for writing the displayed data in the buffer.
A.Update the data only when the panel is not displayed.
When REG[58h]bit[2:0]=110, the undisplayed period is indicated when the TE signal is L.
Q04. Please provide the setting example for switching the full screen display using the double buffer.
A.
- Double buffer ON (REG[36h]bit7=1).
- Set the start/end positions (REG[38h]-REG[46h]) to full screen.
- Write the same background data to Buffer 1 and Buffer 2.
- Full screen display (REG[36h]bit6=1) with the double buffer.
Q05. Please provide the setting example for switching the overlay display using the double buffer.
A.
- Double buffer ON (REG[36h]bit7=1)
- Set the start/end positions (REG[38h]-REG[46h]) to full screen.
- Write the same background data to Buffer 1 and Buffer 2.
- Set the start/end positions (REG[38h]-REG[46h]) to the overlay area.
- Alternately write the images to Buffer 1 and Buffer 2.
- Full screen display (REG[36h]bit6=1) with double buffer.
Q06. Please provide the setting example for changing the overlay display range every time.
A.
- Set the start/end positions (REG[38h]-REG[46h]) to full screen.
- Write the background data to the buffer.
- Set the start/end positions (REG[38h]-REG[46h]) to the overlay area.
- Write the overlay image to the buffer.
- Set the start/end positions (REG[38h]-REG[46h]) to the overlay area.
- Write the background data to the buffer.
- Set the start/end positions (REG[38h]-REG[46h]) to the overlay area to be modified.
- Write the overlay image to the buffer.
Repeat 5) to 8).
