TMS320F28388D: peripheral access way

Huihuang Chen

Hi Champ,

As i know for ADC module, no matter it is assigned to CPU1 or CPU2(), both CPU1 and CPU2 could access to ADC result register.

May i know any other peripherals (for examle: ePWM, eCAP, GPIO, DCAN,MCAN.) have similar access way (ie. one peripheral assigned to CPU1, but CPU2 could access to some register of this peripheral )?

thanks!

Just to be clear, ADC access vs ADCRESULT access are different. It does matter which CPU owns an ADC. But ADC RESULTS is accessible by both.

They are different BASE ADDRESSES in the architecture.

Nima,

Of course , i know ADC access vs ADCRESULT access are different and It does matter which CPU owns an ADC. But ADC RESULTS is accessible by both. 。

But i don't think you answered my question.

Let me see if I can find a consolidated list of the MEMORY REGIONS that are readable by both CPUs and are associated to peripherals.

As discussed, you can used the GPIO READ registers using both CPUs. That should be the other module which have mirrored registers
