EXTI external interrupt selection register
| EXTI8 | EXTI8 GPIO port selection These bits are written by software to select the source input for EXTIm external interrupt. When EXTI_PRIVCFGR.PRIV8 is disabled, EXTI8 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR.PRIV8 is enabled, EXTI8 can only be accessed with privileged access. Unprivileged write to this bit is discarded. Others: reserved 0 (B_0x0): PA[8] pin 1 (B_0x1): PB[8] pin 2 (B_0x2): PC[8] pin |
| EXTI9 | EXTI9 GPIO port selection These bits are written by software to select the source input for EXTI9 external interrupt. When EXTI_PRIVCFGR.PRIV9 is disabled, EXTI9 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR.PRIV9 is enabled, EXTI9 can only be accessed with privileged access. Unprivileged write to this bit is discarded. Others: reserved 0 (B_0x0): PA[9] pin 2 (B_0x2): PC[9] pin |
| EXTI10 | EXTI10 GPIO port selection These bits are written by software to select the source input for EXTI10 external interrupt. When EXTI_PRIVCFGR.PRIV10 is disabled, EXTI10 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR.PRIV10 is enabled, EXTI10 can only be accessed with privileged access. Unprivileged write to this bit is discarded. Others: reserved 0 (B_0x0): PA[10] pin 1 (B_0x1): PB[10] pin 2 (B_0x2): PC[10] pin |
| EXTI11 | EXTI11 GPIO port selection These bits are written by software to select the source input for EXTI11 external interrupt. When EXTI_PRIVCFGR.PRIV11 is disabled, EXTI11 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR.PRIV11 is enabled, EXTI11 can only be accessed with privileged access. Unprivileged write to this bit is discarded. Others: reserved 0 (B_0x0): PA[11] pin 2 (B_0x2): PC[11] pin |
