Detailed Instruction Descriptions
1. Display blink........................................<Blinks the display.>
2. Display on/off control ..........................<Turns the display on or off.>
M, A: Data that specifies the blinking operation

Each bit Gn (where n is an integer between 1 and 16) specifies that blinking be applied to grid output pin Gn when
the corresponding bit Gn is 1.
This instruction is used to specify the blinking operation. Not only can an arbitrary digit be specified, but MDATA
and ADATA can also be specified. There are also seven blinking periods.
Note: 1. When the blinking period needs to be controlled precisely the display should be blinked by repeatedly
*: Don’t care.
