Register block

Fields

moder: MODER

0x00 - GPIO port mode register

otyper: OTYPER

0x04 - GPIO port output type register

ospeedr: OSPEEDR

0x08 - GPIO port output speed register

pupdr: PUPDR

0x0c - GPIO port pull-up/pull-down register

idr: IDR

0x10 - GPIO port input data register

odr: ODR

0x14 - GPIO port output data register

bsrr: BSRR

0x18 - GPIO port bit set/reset register

lckr: LCKR

0x1c - This register is used to lock the configuration of the port bits when a correct write sequence is applied to bit 16 (LCKK). The value of bits [15:0] is used to lock the configuration of the GPIO. During the write sequence, the value of LCKR[15:0] must not change. When the LOCK sequence has been applied on a port bit, the value of this port bit can no longer be modified until the next MCU reset or peripheral reset.A specific write sequence is used to write to the GPIOx_LCKR register. Only word access (32-bit long) is allowed during this locking sequence.Each lock bit freezes a specific configuration register (control and alternate function registers).

afrl: AFRL

0x20 - GPIO alternate function low register

afrh: AFRH

0x24 - GPIO alternate function high register
