Keyscan
Keyscan starts when the key status is changed, or when the "Keyscan Start + key data output"
command is entered. Scan continues until the "Keyscan Stop" command is entered. (Scan is in
stop state at power-on reset.)
When 1 keyscan cycle ends, the INT signal goes to "H" level, so this signal can be used as an
interrupt flag. The INT signal is reset when the LOAD pulse is input after the key data is output,
when the "Keyscan Stop" command is entered, or when a reset signal is applied.

Notes: 1. A recognition error (that is, a switch that was not pressed is recognized as being
pressed) may occur when three or more key switches are pressed at the same time.
If simultaneous pressing of three or more key switches must be recognized, insert
diodes serially to each switch. If simultaneous pressing of three or more key switches
is required not to be recognized, a possible approach is to program so that the entire
key information will be ignored if there are three or more 1s in read data.
2. A change of key status is detected as a change of column inputs (
C0
-
C4
). Therefore
if multiple switches which connected to the same column are pressed at the same
time, it will not be detected as a change of key status.
