WebMar 9, 2024 · Some compilers are bitband aware and may automatically optimise single bit bitfield access using bitbanding. So for example; struct { bit1 : 1 ; bit2 : 1 ; } bits __attribute__ ((section ("BITBANDABLE"))); The compiler (at least armcc v5) may optimise this to utilise the bitband access to bits.bit1 and bits.bit2. YMMV.
