3.1.1. Binary compatibility with other Cortex processors

The processor implements the Armv7-M instruction set and features provided by the Armv7-M architecture profile, and is binary compatible with the instruction sets and features implemented in other Cortex-M profile processors. You cannot move software from the Cortex-M7 processor to:

Code designed for other Cortex-M processors is compatible with Cortex-M7 as long as it does not rely on bit-banding.

To ensure a smooth transition, Arm recommends that code designed to operate on other Cortex-M profile processor architectures obey the following rules and that you configure the Configuration and Control Register (CCR) appropriately:
