The host and eTPU are performing read-modify-writes but the eTPU is overwriting the host's update. Is this a bug?

eTPU_C

I'm having problems when the host and eTPU are using variables in the same PRAM word. Both are performing read-modify-write sequences on their own words, but the eTPU is overwriting the host's update. Is this a bug?

No, but it will require you to use semaphores to arbitrate access to the PRAM location.
