MCT8316AEVM: Register Setting

?? ??

Part Number: MCT8316AEVM
Other Parts Discussed in Thread: MCT8316A, MCF8316A

Hi Team,

I rotate a motor using external PWM signal. I usually rotate the motor as follows: 1. Turn on power supply, 2. Connect USB cable, 3. Load registers, 4. Disconnect USB cable, 5. Send PWM signals.

After I turn off power supply, I turn on power supply again and send PWM signals. In this case, the motor does not rotate. To rotate the motor, I have to connect USB and load registers again.

Is it because register setting is initialized after turning off power supply? If so, is there any way to memorize the register setting even after turning off power supply, because I want to incorporate MCT8316A in the device in the future?

Regards,

Hideyuki

Hi Andrew,

Ten days have passed since I got a reply from you.

I'm sorry to rush you, but I'm worried that you or a team member might forget my question.

Best Regards,

Hi Hideyuki-san,

Apologies for the delay - to answer your question,

For the MCF8316A device, you should be able to save the default register settings via EEPROM programming, so that the desired values are retained even during the event of a power cycle reset. Please refer to the official datasheet section outlining the EEPROM programming process, since I think the issue might be that the customer is not saving it properly
