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.
Fig. 5 Setting example all matrix-outline area
4. Blinking mode
Two patterns blinking by register BLINK3 (address 2A916) or BLINK
bit of display RAM.
Blinking mode is shown in Table 9 (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.
