TMS320F28P659DK-Q1: Dx memory allocation to CPU 2

Pourya Shamsi

Tool/software:

Datasheet says I need to use MCUCNF1 to allocate Dx memories to CPU 1 or 2.

But everywhere claims that particular register is to set the lockstep conditions (top of page 328: MCU Configuration register for LockStep Feature on device)

Also, in the manual (https://www.ti.com/lit/ug/spruiz1b/spruiz1b.pdf?ts=1736127458001) page 328, it states those are read only bits.

So how can I allocate these memories to CPU 2?

Regards,

I think there is some issue here. Let me check and get back to you.

Documentation need to correction. Those bits are R/W and description also need to be updated. We'll update it in our next revision.
