Manufacturer Part Number
s908qy2ad1vdwer
Description
Mc68hc908qt4a Microcontroller
Manufacturer
Freescale Semiconductor, Inc
Datasheet
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
