TRF7960 STM32F407 SPI communication issue

Hi -

 

We are trying to integration TRF7960 with our custom hardware which has STM32F407 processor (via SPI). As per errata 1.1 on TRF7960, we need to switch the polarity of clock during write & read operation (Errata & work around link: http://www.ti.com/lit/an/sloa140a/sloa140a.pdf).

 

What is the best way to change SPI clock and data polarity without re-initialization of SPI between read & write cycles?

 

Thank you in advance. Looking forward for any help. 

 

Regards,

Piyush
