7-6WAKE_CONFIGR/W00bWake pin configuration: Note: Pulse requires more programming
00b = Bi-directional - either edge
01b = Rising edge
10b = Falling edge
11b = Pulse
5-4WAKE_STATR/W0C/H00bStatus of the WAKE pin
00b = No change
01b = Rising edge
10b = Falling edge
11b = Pulse
Note: The status of the WAKE pin is displayed here after a state change. 00 must be written to these bits to clear the change. For Filtered WAKE Rising or falling edge is displayed depending upon selected method from register 12h[7]
3-2WAKE_WIDTH_INVALIDR/W01bPulses less than or equal to these pulses are considered invalid
00b = 5ms and sets tWAKE_WIDTH_MIN to 10ms
01b = 10ms and sets tWAKE_WIDTH_MIN to 20ms
10b = 20ms and sets tWAKE_WIDTH_MIN to 40ms
11b = 40ms and sets tWAKE_WIDTH_MIN to 80ms
1-0WAKE_WIDTH_MAXR/W00bMaximum WAKE pin input pulse width to be considered valid.
00b = 750ms
01b = 1000ms
