3.5.1 Wake Pushbutton

There is a WAKE pushbutton circuit to easily wake the TCAN1162-Q1 from sleep mode. The WAKE pin by default is biased to VSUP on startup. The WAKE pushbutton circuit works by pulling the WAKE pin to ground, causing a logic state change on the pin. To verify the function, place the device into sleep mode, then push down S1, and monitor the INH pin. The INH pin should be in a low logic state before the button is pushed, then pulled up to battery after the button is pushed.
