56F80x SPI receiver lookup issue

Aili — Fri, 13 Nov 2015 00:25:47 GMT

Hi,

I found 56F807 SPI receiver (slave mode) is not able to re-initialize if it misses clock. I have to physically recycle the power to have it work again. Does anyone have solutions?

This issue was also reported here but nobody answered: www.dsprelated.com / showthread/motoroladsp / 1274-1.phphttp://www.dsprelated.com/showthread/motoroladsp/1274-1.php

Thanks,

Liping

Hi, LiPing,

Sorry for the delay. Regarding your question, I suppose that you want to reinitialize the SPI receiving shift register, as you know the SPI receiving shift register is invisible by7 software. In the case, I suggest you clear the CPHA bit, the SPI receiving shift register will be initialized after the falling edge of chip select signal /SS with the CPHA bit cleared.

Hope it can help you.
