WebOct 19, 2024 · In case of GPIO configuration registers of STM32, we can perform atomic write operations using the dedicated BSRR and BRR registers. BSRR is a 32-bit register where the lower 16-bits are used to set any of the 16 pins and the higher 16-bits to clear/reset any of the 16 pins of a particular IO port. The BRR register’s higher 16-bits are ...
