Semiconductor Keyscan
MSM9006-01,
Keyscan starts when status changed, when "Keyscan Start data output" command entered. Scan continues until "Keyscan Stop" command entered. (Scan stop state power-on reset.) When keyscan cycle ends, signal goes level, this signal used interrupt flag. signal reset when LOAD pulse input after data output, when "Keyscan Stop" command entered, when reset signal applied.

Notes: recognition error (that switch that pressed recognized being pressed) occur when three more switches pressed same time. simultaneous pressing three more switches must recognized, insert diodes serially each switch. simultaneous pressing three more switches required recognized, possible approach program that entire information will ignored there three more read data. change status detected change column inputs C4). Therefore multiple switches which connected same column pressed same time, will detected change status.

Upon power-on reset, display state. turn display, enter Display command. Regardless display data, display goes entering Display command because Display command turns segments display changes state output port from level. display returns initial state entering Display command because Display command resets off-state display.
