10. Key Scan 

There is a key scanner built in the SH69P55A/69K55A, which can automatic detect the key-press. It includes four outputs 
(KEY_O1 - 4, shared with COM1 - COM4), five inputs (KEY_I5 - 1, shared with SEG1 - SEG5), and it can detect 20 individual 
keys. The key scan function must be shared with LCD or LED function, so the key scan must work in proper LCD or LED mode. 
Since the LCD/LED drive waveform integrates the key scan waveform, the LCD/LED drive waveform is enlarged by a duty 
period compared with the traditional waveform. For instance, 1/4 duty would be enlarged to1/5 duty. The additional duty period is 
used to scan keys, and it would be inserted into the end of the frame automatically. The LCD waveform scans keys one time 
every one frame. The key scanner only works a duty period for each frame and it does not work for the rest duty periods of the 
frame. It scans keys during the last duty period of the first half frame, but it does not work during the last duty period of the last 
half frame. For instance in 1/4 duty mode the key scanner only works during the last duty period of the first half frame, but it does 
not work during the rest 9 duty periods of the frame. The LED waveform scans keys one time every two frame. The key scanner 
only works a duty period for every two frames and it does not work for the rest duty periods of the two frames. It scans keys 
during the last duty period of one frame, but it does not work during the last duty period of the next frame. For instance in 1/4 
duty mode the key scanner only works a duty period for every two frames and it does not work during the rest 9 duty periods of 
the two frames. 
Once the end of the key scan reaches, the key interrupt request flag would be set (KEYIF) whether a key is pressed or not. In 
LCD mode the key interrupt request flag is set every one frame. In LED mode the key interrupt request flag is set every 2 
frames.
