180 / 303 page  APPLICATION 5.1 Example of multi-line display 5-7 7220 Group User’s Manual 5.1.5 Line counter The line counter determines which line of display data is to be set. For example, if a CRT interrupt occurs at the end of the first line display, the line counter value will be “2.” Therefore, the 3rd line display data must be set from the end of the 1st line display to the start of the 3rd line display. Then, the line counter value is incremented and becomes “3.” Figure 5.1.7 shows the example of the setup timing for the line counter and the display character data. Fig. 5.1.7 Example of setup timing for line counter and display character data The 1st line (block 1) The 2nd line (block 2) The 3rd line (block 1) The 11th line (block 1) Line counter value 2 3 4 0 Line counter value : 2 CRT interrupt Set 3rd line display data by the start of 3rd line display ↓ Line counter value: 3 The 12th line (block 2) 1 The 4th line (block 2) A Start of the 3rd line display End of the 1st line display |
