Set by hardware when the Port line 6 detects a programmed level. It generates a
Keyboard interrupt request if the KBIE. 6 bit in KBIE register is set.
Must be cleared by software.
5
KBF5
Keyboard line 5 flag
Set by hardware when the Port line 5 detects a programmed level. It generates a
Keyboard interrupt request if the KBIE. 5 bit in KBIE register is set.
Must be cleared by software.
4
KBF4
Keyboard line 4 flag
Set by hardware when the Port line 4 detects a programmed level. It generates a
Keyboard interrupt request if the KBIE. 4 bit in KBIE register is set.
Must be cleared by software.
3
KBF3
Keyboard line 3 flag
Set by hardware when the Port line 3 detects a programmed level. It generates a
Keyboard interrupt request if the KBIE. 3 bit in KBIE register is set.
Must be cleared by software.
2
KBF2
Keyboard line 2 flag
Set by hardware when the Port line 2 detects a programmed level. It generates a
Keyboard interrupt request if the KBIE. 2 bit in KBIE register is set.
