Keyboard Interrupt Module (KBI)
20.6 Keyboard Interrupt Registers
20.6.1 Keyboard Status and Control Register
Data Sheet
412
Address:
Two registers control the operation of the keyboard interrupt module:
KEYF — Keyboard Flag Bit
ACKK — Keyboard Acknowledge Bit
Reset:
Read:
Write:
Figure 20-3. Keyboard Status and Control Register (KBSCR)
This read-only bit is set when a keyboard interrupt is pending.
Reset clears the KEYF bit.
Writing a logic 1 to this write-only bit clears the keyboard interrupt
request. ACKK always reads as logic 0. Reset clears ACKK.
1 = Keyboard interrupt pending
0 = No keyboard interrupt pending
Keyboard status and control register (KBSCR)
Keyboard interrupt enable register (KBIER)
Flags keyboard interrupt requests
Acknowledges keyboard interrupt requests
Masks keyboard interrupt requests
Controls keyboard interrupt triggering sensitivity
