3. Setting matrix outline
The ALL24 register (address 2AF16) allows you to set a matrix
out-line. A matrix outline can be set for each line by using the
DSP1XX register (address 2AC16) .
However, this setting is inhibited if the EX register (address 2B016)
is 0 (external sync). An example of how you set a matrix outline is
shown in Figure 5.

4. Blinking mode
Two patterns blinking by register BLINK3 (address 2A916) or
BLINK bit of display RAM.
Blinking mode is shown in Table 11 (SYRAM do not blink).
Use registers BLINK0, 1, and 2 (address 2A916) to set the duty
ratio and period that determines the blinking time. Tables 12 and
13 list the relationship between the register settings and the duty
ratio and pe-riod.
