Reduced overhead on digital signal processing for motor drive applications

1. A monostable multivibrator communicatively coupled to a host device and an external analog-to-digital converter, the monostable multivibrator configured to:

receive a chip select signal from the host device, the chip select signal going low to trigger the monostable multivibrator to provide the monostable pulse; and

generate, in response to the chip select signal, a conversion start signal to the external analog-to-digital converter, the conversion start signal comprising the monostable pulse provided by the monostable multivibrator to the external analog-to-digital converter; and

control a pulse width of the monostable pulse by a resistor-capacitor circuit of the monostable multivibrator.

2. The monostable multivibrator of claim 1 , wherein the monostable multivibrator utilizes when the chip select signal goes low as a trigger to generate the conversion start signal.

3. The monostable multivibrator of claim 2 , wherein the monostable multivibrator is configured to repeat in each cycle as the chip select signal goes low the conversion start signal.

4. The monostable multivibrator of claim 1 , wherein the host device is configured to enable a delay between the chip select signal and an application of a clock to allow a conversion.

5. The monostable multivibrator of claim 1 , wherein the host device is configured to utilize a serial peripheral interface enable signal to control an application of a serial clock.

6. The monostable multivibrator of claim 1 , wherein a busy signal from the external analog-to-digital converter indicates a completion of a conversion.

7. The monostable multivibrator of claim 1 , wherein the host device is a digital signal processor.
