Register block

Fields

gpioa_moder: GPIOA_MODER

0x00 - GPIO port mode register

gpioa_otyper: GPIOA_OTYPER

0x04 - GPIO port output type register

gpioa_ospeedr: GPIOA_OSPEEDR

0x08 - GPIO port output speed register

gpioa_pupdr: GPIOA_PUPDR

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

gpioa_idr: GPIOA_IDR

0x10 - GPIO port input data register

gpioa_odr: GPIOA_ODR

0x14 - GPIO port output data register

gpioa_bsrr: GPIOA_BSRR

0x18 - GPIO port bit set/reset register

gpioa_lckr: GPIOA_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).

gpioa_afrl: GPIOA_AFRL

0x20 - GPIO alternate function low register

gpioa_afrh: GPIOA_AFRH

0x24 - GPIO alternate function high register
