KEY SCAN DURING NORMAL MODE The pins KS1 to KS6 are set high. A key scan starts if any key is pressed, and the scan continues until all keys have been released. Multiple key pressed can be recognized be determining ...
Page 11
MULTIPLE KEY PRESSES Without the insertion of additional diodes, the PT6552 supports key scan for double key presses in general, triple key presses of keys on the lines for input pins KI1 to KI5, and multiple key pressed of keys ...
