摘要： A microcontroller having digital to frequency converter and pulse frequency modulator capabilities. The digital to frequency converter (DFC) generates a 50 percent duty cycle square wave signal that may be varied in frequency, wherein the 50 percent duty cycle square wave signal is directly proportional and linear with a count value put into an increment register. The pulse to frequency modulator (PFM) generates pulses having pulse widths of the input clock for each rollover of a counter. The frequency of these pulses is directly proportional and linear with the count value put into the increment register.

摘要： A monitoring and protection circuit associated with a voltage regulator supplying power to a CMOS device can sense over current levels precisely enough for determining if a fault has occurred in a circuit of the CMOS device, e.g., latch-up, failed or shorted transistor, etc., then this monitoring and protection circuit may automatically generate a fault alert signal and/or cycle power to the CMOS device when an unexpected over current may occur, e.g., CMOS circuit latch-up. The monitoring and protection circuit may be integrated with a voltage regulator, e.g., low drop-out (LDO) voltage regulator on a single integrated circuit substrate. The monitoring and protection circuit and voltage regulator may be fabricated with a CMOS device, e.g., digital processor on a single integrated circuit substrate.

摘要： A special test mode is incorporated within a USB transceiver of a digital system, and when the special test mode is activated, USB eye pattern test data signal waveforms, e.g., a continuous stream of USB state transitions (defined by the USB specification) are transmitted on the USB data lines connected to the USB transceiver. Conventional test equipment may be attached to the USB data lines and the signal quality monitored. Circuit changes can be made to the digital system and the results easily measured. When the USB eye pattern test data signal waveforms on the USB data lines of the digital system are of satisfactory quality, the special test mode may be turned off and the USB transceiver will resume operation as a normal USB device.
