Assignee: LATTICE SEMICONDUCTOR CORPORATION
Field: Basic communication processes (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 2:
3. The adaptive POR signal generator of claim 1, further comprising:
a ramp traversal detector configured to receive the ramp voltage from the ramp voltage selector and provide a ramp traversal signal to the logic device; and
a counter configured to receive counter control signals from the logic device and count incrementally and/or decrementally based, at least in part, on the counter control signals provided by the logic device;
wherein the detecting the first supply voltage ramp traversal comprises:
detecting a first logic signal transition corresponding to the first supply voltage ramp traversal in the ramp traversal signal generated by the ramp traversal detector; and
initiating an incrementing count by the counter; and

wherein the detecting the second supply voltage ramp traversal comprises:
detecting a second logic signal transition corresponding to the second supply voltage ramp traversal in the ramp traversal signal generated by the ramp traversal detector; and
halting the incrementing count by the counter at a ramp time count corresponding to the amount of time between the first and second supply voltage ramp traversals.
