Writing a ‘0’ or a ‘1’ into this bit will erase all the bits (including this one) of the KBFR register

• Bit 2 - KBF2 : Keyboard Flag for KbIN2 pin

Set by hardware when the pin function KbIN2 (PA2) detects a programmed level. It generates a

Keyboard interrupt request if the KBER.KBE2 bit is set.

Writing a ‘0’ or a ‘1’ into this bit will erase all the bits (including this one) of the KBFR register

• Bit 1 - KBF1: Keyboard Flag for KbIN1 pin

Set by hardware when the pin function KbIN1 (PA1) detects a programmed level. It generates a

Keyboard interrupt request if the KBER.KBE1 bit is set.

Writing a ‘0’ or a ‘1’ into this bit will erase all the bits (including this one) of the KBFR register

• Bit 0 - KBF0 : Keyboard Flag for KbIN0 pin

Set by hardware when the pin function KbIN0 (PA0) detects a programmed level. It generates a

Keyboard interrupt request if the KBER.KBE0 bit is set.

Writing a ‘0’ or a ‘1’ into this bit will erase all the bits (including this one) of the KBFR register
