Description

EXTI falling trigger selection register 2

Fields

FT46	Falling trigger event configuration bit of configurable event input x sup (1) /sup When EXTI_SECCFGR.SECx is disabled, FTx can be accessed with non-secure and secure access. When EXTI_SECCFGR.SECx is enabled, FTx can only be accessed with secure access. Non-secure write to this FTx is discarded, non-secure read returns 0. When EXTI_PRIVCFGR.PRIVx is disabled, FTx can be accessed with unprivileged and privileged access. When EXTI_PRIVCFGR.PRIVx is enabled, FTx can only be accessed with privileged access. Unprivileged write to this FTx is discarded, unprivileged read returns 0. 0 (B_0x0): Falling trigger disabled (for event and Interrupt) for input line 1 (B_0x1): Falling trigger enabled (for event and Interrupt) for input line.
FT50	Falling trigger event configuration bit of configurable event input x sup (1) /sup When EXTI_SECCFGR.SECx is disabled, FTx can be accessed with non-secure and secure access. When EXTI_SECCFGR.SECx is enabled, FTx can only be accessed with secure access. Non-secure write to this FTx is discarded, non-secure read returns 0. When EXTI_PRIVCFGR.PRIVx is disabled, FTx can be accessed with unprivileged and privileged access. When EXTI_PRIVCFGR.PRIVx is enabled, FTx can only be accessed with privileged access. Unprivileged write to this FTx is discarded, unprivileged read returns 0. 0 (B_0x0): Falling trigger disabled (for event and Interrupt) for input line 1 (B_0x1): Falling trigger enabled (for event and Interrupt) for input line.
FT53	Falling trigger event configuration bit of configurable event input x When EXTI_SECCFGR.SECx is disabled, FTx can be accessed with non-secure and secure access. When EXTI_SECCFGR.SECx is enabled, FTx can only be accessed with secure access. Non-secure write to this FTx is discarded, non-secure read returns 0. When EXTI_PRIVCFGR.PRIVx is disabled, FTx can be accessed with unprivileged and privileged access. When EXTI_PRIVCFGR.PRIVx is enabled, FTx can only be accessed with privileged access. Unprivileged write to this FTx is discarded, unprivileged read returns 0. 0 (B_0x0): Falling trigger disabled (for event and Interrupt) for input line 1 (B_0x1): Falling trigger enabled (for event and Interrupt) for input line.
