Question about Cortex bit-banding feature

2016-07-29 Thread Fredrik Hederstierna
Some processor architectures do support bitwise access to memory, eg. ARM Cortex-M and 8051 (by ARM called bit-banding). In these architectures a single bit can somewhat be addressable, but only as an 'aliased' memory region for another memory address. I noticed that Keil ARMCC compiler now seem
