Symbol
Scroll area line count register (00H to AFH)
Partial 1 display area line count register (00H to AFH)
Partial 2 display area line count register (00H to AFH)
Sets the maximum value of the Y address in the window access mode.
The Y address is incremented up to the address value set by this command, and then
initialized to the minimum address value set by the MIN. Y address register (R10)
(R5: YDIR = 0)
Set a value between 01H to AFH.
These bits are used for reading/writing data from/to display memory (internal RAM).
Scroll area start line register (00H to AFH)
When the screen is scrolled, the screen of the number of lines set by the scroll area line count
register (R16) is scrolled up by the number of steps set by the scroll step count register (R17),
starting from the line set by this command.
When the screen is scrolled, the screen of the number of lines set by this command is scrolled
up by the number of steps set by the scroll step count register (R17), starting from the line set
by the scroll area start line register (R15)
Scroll step count register (00H to AFH)
When the screen is scrolled, the screen of the number of lines set by the scroll area line count
register (R16) and the scroll step count register (R17) is scrolled up by the number of steps set
by this command.
Note that because this command is invalid in the partial display mode, the scroll function
cannot be used.
Partial off area color register
Sets the color of the screen other than the partial display area during partial display (R0: DTY
= 1). One of eight colors can be selected (RGB: 1 bit each) as the off color.
The relationship between each color data and the bits of this register is as follows. This
relationship is not dependent upon the value of ADC.
PGR: R OFF= 0, ON = 1
PGG: G OFF= 0, ON = 1
PGB: B OFF= 0, ON = 1
Partial 1 display area start line register (00H to AFH)
During partial display (R0: DTY = 1), the area starting from the line set by this command and
ending as set by the partial 1 display area line count register (R22) is the partial 1 display area.
Partial 2 display area start line register (00H to AFH)
During partial display (R0: DTY = 1), the area starting from the line set by this command and
ending as set by the partial 2 display area line count register (R23) is the partial 2 display area.
An area starting from the line set by the partial 1 display area start register (R20) and ending
as set by this command is the partial 1 display area.
If this register is 0, the values of the partial 2 display area start line register (R29) and the
partial 2 display area line count register (R31) are not valid.
An area starting from the line set by the partial 2 display area start register (R21) and ending
as set by this command is the partial 2 display area.
If the partial 1 display area line count register is 0, the values of the partial 2 display area start
line register (R21) and partial 2 display area line count register (R23) are not valid.
