14.9.2 Keyboard Interrupt Enable Register
MC68HC908JB8•MC68HC08JB8•MC68HC08JT8 — Rev. 2.3
Freescale Semiconductor
Address: $0017
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
Reset:
Read:
Write:
Each of these read/write bits enables the corresponding keyboard
interrupt pin to latch interrupt requests. Reset clears the keyboard
interrupt enable register.
