Abstract: An apparatus includes a debugger circuit, debug pins, and a test controller circuit. The test controller circuit is configured to, in a programming mode, determine a subset of the debug pins used in programming the apparatus. The test controller circuit is further configured to save a designation of the subset of the debug pins. The test controller circuit is further configured to, in a test mode subsequent to the programming mode, use the designation to route the subset of the debug pins used in programming the apparatus to the debugger circuit for debug input and output with the server.

Abstract: A temperature-compensating clock frequency monitor circuit may be provided to detect a clock pulse frequency in an electronic device that may cause erratic or dangerous operation of the device, as a function of an operating temperature of the device. The temperature-compensating clock frequency monitor circuit include a temperature sensor configured to measure a temperature associated with an electronic device, a clock having an operating frequency, and a frequency monitoring system. The frequency monitoring system may be configured to determine the operating frequency of the clock, and based at least on (a) the operating frequency of the clock and (b) the measured temperature associated with the electronic device, generate a corrective action signal to initiate a corrective action associated with the electronic device or a related device. The temperature sensor, clock, and frequency monitoring system may, for example, be provided on a microcontroller.

Abstract: A plurality of PWM generators have user configurable time delay circuits for each PWM control signal generated therefrom. The time delay circuits are adjusted so that each of the PWM control signals arrive at their associated power transistors at the same time. This may be accomplished by determining a maximum delay time of the PWM control signal that has to traverse the longest propagation time and then setting the delay for that PWM control signal to substantially zero delay. Thereafter, all other delay time settings for the other PWM control signals may be determined by subtracting the propagation time for each of the other PWM control signals from the longest propagation time. Thereby insuring that all of the PWM control signals arrive at their respective power transistor control nodes with substantially the same time relationships as when they left their respective PWM generators.
