8.8.3 Keyboard Interrupt Polarity Register (KBIPR)
KBIPR determines the polarity of the enabled keyboard interrupt pin and enables the appropriate pullup
or pulldown device.
KBIP5–KBIP0 — Keyboard Interrupt Polarity Bits
Freescale Semiconductor
Each of these read/write bits enables the polarity of the keyboard interrupt detection.
1 = Keyboard polarity is high level and/or rising edge
0 = Keyboard polarity is low level and/or falling edge
