Datasheet
MODEK — Keyboard Triggering Sensitivity Bit
13.7.2 Keyboard Interrupt Enable Register
The keyboard interrupt enable register enables or disables each port A pin to operate as a keyboard
interrupt pin.
KBIE3–KBIE0 — Keyboard Interrupt Enable Bits
Freescale Semiconductor
This read/write bit controls the triggering sensitivity of the keyboard interrupt pins. Reset clears
MODEK.
Each of these read/write bits enables the corresponding keyboard interrupt pin to latch interrupt
requests. Reset clears the keyboard interrupt enable register.
1 = Keyboard interrupt requests on falling edges and low levels
0 = Keyboard interrupt requests on falling edges only
1 = PTAx pin enabled as keyboard interrupt pin
0 = PTAx pin not enabled as keyboard interrupt pin
Address: $001B
