Window access mode setting
Sets the maximum value of the X address in the window access mode.
Sets the bus width when the parallel interface is used.
0: 16-bit data bus
1: 8-bit data bus
This command is invalid when the serial interface is used.
Sets the write mode for writing data to the display RAM.
If the high-speed RAM write mode is selected, data is written to the display RAM in 64-bit units
inside the
to the display RAM in 64-bit units.
0: Normal write mode (16-bit access)
1: High-speed RAM write mode (64-bit access)
When the window access mode is set, the address is incremented/decremented only in the
range set by the MIN
MIN
0: Normal operation
1: Window access mode
Selects the direction in which the display RAM address is to be incremented/decremented.
Whether the X address and Y address are incremented or decremented is specified by XDIR
(R5: D
0: Access in X address direction
1: Access in Y address direction
Specifies whether the display RAM address is incremented or decremented in the X address
direction.
0: Increments X address
1: Decrements X address
Specifies whether the display RAM address is incremented or decremented in the Y address
direction.
0: X address increment
1: X address decrement
This register sets the X address of the display RAM.
Set a value between 00H and 83H.
This register sets the Y address of the display RAM.
Set a value between 00H and AFH.
Sets the minimum value of the X address in the window access mode.
The X address is incremented up to the maximum value set by the MAX
(R9), and then initialized to the address value set by this command. (R5: XDIR = 0)
Set a value between 00H to 82H.
The X address is incremented up to the maximum value set by the MIN
(R8), and then initialized to the address value set by this command. (R5: XDIR = 0)
Set a value between 01H to 83H.
Sets the minimum value of the T address in the window access mode.
The Y address is incremented up to the maximum value set by the MAX
(R11), and then initialized to the address value set by this command.
