Timing characteristics
VDD = 3.3 V, TA = -20 to 70°C, unless otherwise noted. Typical values are at TA = 25°C
Figure 55.
Key scanning and display timing
Note:
Pulse width of segment signal is decided by oscillator frequency. The value can be modified
by trimming ROSC. One cycle of key scanning consists of one frame and data of 12 x 2
matrices are stored in RAM.
The keyscan is only at the end of the frame when the display is ON. When the display is
OFF, the key scan takes place continuously. The grid is turned off during the key scan.
