(1) This parameter is valid only when register 11h[7:6] = 11b

(2) This is the minimum pulse width for a WAKE pin input that device will detect as a good pulse. Values between the min t_{WK_WIDTH_MIN} and max t_{WK_WIDTH_INVALID} are indeterminate and may or may not be considered valid. This parameter works with t_{WK_WIDTH_MIN} to determine if a WAKE input pulse is valid

(3) Dependent upon V_CC and V_IO being above UV_CC and UV_IO after INH turns on node power.

(4) t_{WK_WIDTH_INVALID} sets this value by using register 11h[3:2]
