Freescale Semiconductor MPC5604B - Wakeup;Interrupt Filter Enable Register (WIFER)

MPC5604B/C Microcontroller Reference Manual, Rev. 8
Freescale Semiconductor 237
12.4.9 Wakeup/Interrupt Filter Enable Register (WIFER)
This register is used to enable an analog filter on the corresponding interrupt pads to filter out glitches on
the inputs.
NOTE
There is no analog filter for the RTC_API.
12.4.10 Wakeup/Interrupt Pullup Enable Register (WIPUER)
This register is used to enable a pullup on the corresponding interrupt pads to pull an unconnected
wakeup/interrupt input to a value of ‘1’.
