Decorated memory store and load for atomic operations
2020-11-04 12:44 PM
There are some families with bit-banded SRAM which allows atomic read/write on bits. Not sure if that's what you're looking for or not.

Thanks for reply,
I'm aware of bit banding feature that is only for atomic set and clear operation on single bit from alias address to sigle bit.
I want to know if there is such atomic load and store for "and or xor bit-field-extract bit-field-insert" from decorated address usage, e.g. BME in NXP mcus.
Sorry for my english i hope to be clear
Thanks

At least GPIO has Bit set and Reset registers for atomic access.
