EXTI external interrupt selection register
| EXTI12 | EXTI12 GPIO port selection These bits are written by software to select the source input for EXTI12 external interrupt. When EXTI_PRIVCFGR.PRIV12 is disabled, EXTI12 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR.PRIV12 is enabled, EXTI12 can only be accessed with privileged access. Unprivileged write to this bit is discarded. Others: reserved 0 (B_0x0): PA[12] pin 1 (B_0x1): PB[12] pin 2 (B_0x2): PC[12] pin |
