Abstract
An automotive control module includes a microcontroller having an access port, and that permits reprogramming of its functions responsive to a voltage at the access port being greater than a first predefined threshold upon power-up or reset thereof. The automotive control module also includes a boot assist control circuit lacking logical elements and including a pair of input ports, an output port directly electrically connected to the access port, and a plurality of capacitors, resistors, and transistors electrically connected between the pair and output port. The plurality outputs a voltage to the output port at least equal to the first predefined threshold responsive to voltages at both the input ports being greater than a second predefined threshold, and outputs a voltage to the output port less than the first predefined threshold responsive to the voltage at either one of the input ports being less than the second predefined threshold.
