STM32H745/755 and STM32H747/757 Bit Banding

[Iraj]

I'm writing software on dual core CPU, 

On M4 core, I need to know is it support bit banding? I searched all documents from ST, but I didn't find clear answer, 

I found on M4 CPU, like STM32F series bit banding has supported, and on M7 single core CPU like STM32H743 doesn't support, but on dual core CPU, like STM32H745 is it support?

As I recollect bit-banding was regarded as a bit of a nightmare, and didn't really resolve any issues, and caused more.

Bit-Banding is not used by either core

Confirm by looking at the memory map, for any secondary decode regions, and grepping source for "_BB_" references.

Bit banding was included in STM32 with Cortex-M3 and Cortex-M4, but no longer in STM32 based on Cortex-M7.
