This percentage deviation is typical change from the individual device oscillator frequency at 25 °C
The 32MHz reference clock.
Minimum pulse to recognize a asynchronous transition
Minimum pulse to recognize a level sensitive
For determination of an actual key/push button in a matrix, this pulse with must remain present for the keyboard scan routine
duration. Thus, the minimum pulse width would be determined by the software, not the detection hardware.
