"WebFeb 18, 2024 · Writing ODR sets all 16 pins at once, e.g. GPIOB->ODR = 0xF00F sets pins B0 through B3 and B12 through B15 to 1, and B4 through B11 to 0, regardless of their previous state. One can write GPIOD->ODR = (1<<4) to set pin GPIOD4 to 1, or GPIOD->ODR &= ~ (1<<4) to reset it. Writing BSRR treats the value written as two bitmasks. " - Gpioc- odr rx 0 8 0x00ff
