Keyboard Interrupt Module (KBI)
9.8.2 Keyboard Interrupt Enable Register (KBIER)
KBIER enables or disables each keyboard interrupt pin.
KBIE5–KBIE0 — Keyboard Interrupt Enable Bits
9.8.3 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
88
Each of these read/write bits enables the corresponding keyboard interrupt pin to latch KBI interrupt
requests.
Each of these read/write bits enables the polarity of the keyboard interrupt detection.
1 = KBIx pin enabled as keyboard interrupt pin
0 = KBIx pin not enabled as keyboard interrupt pin
1 = Keyboard polarity is high level and/or rising edge
0 = Keyboard polarity is low level and/or falling edge
