Keyboard Interrupt Module (KBI)
ACKK — Keyboard Acknowledge Bit
IMASKK — Keyboard Interrupt Mask Bit
MODEK — Keyboard Triggering Sensitivity Bit
9.7.2 Keyboard Interrupt Enable Register
The keyboard interrupt enable register enables or disables each port A pin to operate as a keyboard
interrupt pin
KBIE7–KBIE0 — Keyboard Interrupt Enable Bits
112
Writing a 1 to this write-only bit clears the keyboard interrupt request. ACKK always reads as 0. Reset
clears ACKK.
Writing a 1 to this read/write bit prevents the output of the keyboard interrupt mask from generating
interrupt requests. Reset clears the IMASKK bit.
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 masked
0 = Keyboard interrupt requests not masked
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
