Is M0 core Bit banding capable?

I want to implement semaphores between the two cores using the bit banding region and the AHB SRAM sections.

My implementation works fine on the M4 core but it hards fault while accessing the alias region on the M0.

is the M0 capable of bit banding on the LPC43xx?

If not, how should I implement semaphores between the two cores?

There is a whole section in the UM10503 on inter process communication. See Chapter 2.

and M0 & M0+ cores do not have bit banding (although ARM says it can be added in some cases)
