WebDec 29, 2024 · Byte_offset is the number of the byte in the bit-band region that contains the targeted bit. Bit_number is the bit position (0-7) of the targeted bit. We will use bit-band feature to set a pin high if a button is pressed and set a pin low if it’s released. I will use EFM32LG starter kit ( EFM32LG STK3600) to program the ARM Cortex-M3 CPU. 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.
