This component implements a Keyboard Interrupt Module which allows to catch events on chosen external pins.
These pins share one interrupt which can be caused by multiple events on these pins.
This component is usually used for connecting of a matrix keyboard via external pins.
A version specific information for HCS08 and ColdFire V1 derivatives:
Invert interrupt trigger condition property inverts value in the Pull resistor property if "pull up" is selected (E.g. If Invert interrupt trigger condition property is set to "yes" and Pull resistor property is set to "pull up" then actually pull down resistor is connected on the hardware).

A version specific information for HCS08, RS08 and ColdFire V1 derivatives:
Generate interrupt on property allows to select the generation of the interrupt only on either the low level or falling edge even if any of the pins have more possibilities. Invert interrupt trigger condition property can be used to enable the generation of the interrupt on the high level or rising edge.
