EXTI external interrupt selection register
EXTI8 | EXTI8 GPIO port selection These bits are written by software to select the source input for EXTI8 external interrupt. When EXTI_SECCFGR1.SEC8 is disabled, EXTI8 can be accessed with non-secure and secure access. When EXTI_SECCFGR1.SEC8 is enabled, EXTI8 can only be accessed with secure access. Non-secure write is discarded and non-secure read returns 0. When EXTI_PRIVCFGR1.PRIV8 is disabled, EXTI8 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR1.PRIV8 is enabled, EXTI8 can only be accessed with privileged access. Unprivileged write to this bit is discarded. Others: reserved 0 (B_0x00): PA8 pin 1 (B_0x01): PB8 pin 2 (B_0x02): PC8 pin 3 (B_0x03): PD8 pin 4 (B_0x04): PE8 pin 5 (B_0x05): PF8 pin 6 (B_0x06): PG8 pin 7 (B_0x07): PH8 pin 8 (B_0x08): PI8 pin |
EXTI9 | EXTI9 GPIO port selection These bits are written by software to select the source input for EXTI9 external interrupt. When EXTI_SECCFGR1.SEC9 is disabled, EXTI9 can be accessed with non-secure and secure access. When EXTI_SECCFGR1.SEC9 is enabled, EXTI9 can only be accessed with secure access. Non-secure write is discarded and non-secure read returns 0. When EXTI_PRIVCFGR1.PRIV9 is disabled, EXTI9 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR1.PRIV9 is enabled, EXTI9 can only be accessed with privileged access. Unprivileged write to this bit is discarded. Others: reserved 0 (B_0x00): PA9 pin 1 (B_0x01): PB9 pin 2 (B_0x02): PC9 pin 3 (B_0x03): PD9 pin 4 (B_0x04): PE9 pin 5 (B_0x05): PF9 pin 6 (B_0x06): PG9 pin 7 (B_0x07): PH9 pin 8 (B_0x08): PI9 pin |
EXTI10 | EXTI10 GPIO port selection These bits are written by software to select the source input for EXTI10 external interrupt. When EXTI_SECCFGR1.SEC10 is disabled, EXTI10 can be accessed with non-secure and secure access. When EXTI_SECCFGR1.SEC10 is enabled, EXTI10 can only be accessed with secure access. Non-secure write is discarded and non-secure read returns 0. When EXTI_PRIVCFGR1.PRIV10 is disabled, EXTI10 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR1.PRIV10 is enabled, EXTI10 can only be accessed with privileged access. Unprivileged write to this bit is discarded. Others: reserved 0 (B_0x00): PA10 pin 1 (B_0x01): PB10 pin 2 (B_0x02): PC10 pin 3 (B_0x03): PD10 pin 4 (B_0x04): PE10 pin 5 (B_0x05): PF10 pin 6 (B_0x06): PG10 pin 7 (B_0x07): PH10 pin 8 (B_0x08): PI10 pin |
EXTI11 | EXTI11 GPIO port selection These bits are written by software to select the source input for EXTI11 external interrupt. When EXTI_SECCFGR1.SEC11 is disabled, EXTI11 can be accessed with non-secure and secure access. When EXTI_SECCFGR1.SEC11 is enabled, EXTI11 can only be accessed with secure access. Non-secure write is discarded and non-secure read returns 0. When EXTI_PRIVCFGR1.PRIV11 is disabled, EXTI11 can be accessed with privileged and unprivileged access. When EXTI_PRIVCFGR1.PRIV11 is enabled, EXTI11 can only be accessed with privileged access. Unprivileged write to this bit is discarded.
