Note: TH: the text home address
TA: the width of text area (number of characters /line), to be defined by user.
CL: number of characters/line set by hardware, the CL of this module is 40.

GH: the graphic home address
TA: the width of graphic area (number of characters /line), to be defined by
user.
CL: number of characters/line set by hardware, the CL of this module is 40.
Note: In Text mode or Graphic mode, when TA≠CL, the relationship between the
valid display area of the LCD panel and DDRAM address is detailed in
5-6-2.
5-6．Commands
The command of this module may have one operand datum, or two operand
data or none). It is important to send the data first, and then to send the
command code. If the number of the operand data is more than specified, the
last are valid. The status check must be performed every time before the data
and commands are read or written.
The status word format is as follows:
STA7 STA6 STA5 STA4 STA3 STA2 STA1 STA0
STA0: check command execution capability 1: enable 0: disable
STA1: check data read/write capability
1: enable 0: disable
STA2: check auto mode data read capability 1: enable 0: disable
STA3: check auto mode data write capability 1: enable 0: disable
STA4: not used
STA5: check controller operation capability
1: enable 0: disable
STA6: error flag. Used for screen peek and screen copy commands
1: error
0: no error
STA7: check the blink condition
1: normal display 0: display off
Note:
1. It is necessary to check STA0 and STA1 at the same time. There is a
possibility of erroneous operation due to a hardware interrupt.
2. For most modes STA0/STA1 are used at a status check.
