Description
Keyboard line 7 flag
Set by hardware when the Port line 7 detects a programmed level. It generates a
Keyboard interrupt request if the KBKBIE.7 bit in KBIE register is set.
Cleared by hardware when reading KBF SFR by software.
Keyboard line 6 flag
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.
Cleared by hardware when reading KBF SFR by software.
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.
Cleared by hardware when reading KBF SFR by software.
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.
Cleared by hardware when reading KBF SFR by software.
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.
Cleared by hardware when reading KBF SFR by software.
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.
Cleared by hardware when reading KBF SFR by software.
Keyboard line 1 flag
Set by hardware when the Port line 1 detects a programmed level. It generates a
Keyboard interrupt request if the KBIE.1 bit in KBIE register is set.
Cleared by hardware when reading KBF SFR by software.
Keyboard line 0 flag
Set by hardware when the Port line 0 detects a programmed level. It generates a
Keyboard interrupt request if the KBIE.0 bit in KBIE register is set.
Cleared by hardware when reading KBF SFR by software.
