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). Table 11 Blinking mode Blink OFF Duty 50% 01 Duty 25% Duty 75% 0 1 BLINK0 BLINK1 Table 12 Setting of duty ratio BLINK2 0 1 Cycle Approximately 1 second (Vertical sync divided into 1/64) Approximately 0.5 second (Vertical sync divided into 1/32) Table 13 Setting of cycle 0 BLINK3 Blinking mode at blinking OFF Blinking Normal character, reversed character alternation display 1 Normal Reverse 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. |
