Чо?
вот чё:
Bit band is not supported on TrustZone for ARMv8-M systems. This is due to the need to alias of bit information to two different address which could be in different security domains. For these systems, bit manipulation of peripheral data can be handled at peripheral level (for example, by offering bit set/clear registers) instead.
