Description

EXTI software interrupt event register 2

Fields

SWI46

Software interrupt on event x When EXTI_SECCFGR.SECx is disabled, SWIx can be accessed with non-secure and secure access. When EXTI_SECCFGR.SECx is enabled, SWIx can only be accessed with secure access. Non-secure write to this SWI x is discarded, non-secure read returns 0. When EXTI_PRIVCFGR.PRIVx is disabled, SWIx can be accessed with unprivileged and privileged access. When EXTI_PRIVCFGR.PRIVx is enabled, SWIx can only be accessed with privileged access. Unprivileged write to this SWIx is discarded, unprivileged read returns 0. A software interrupt is generated independent from the setting in EXTI_RTSR and EXTI_FTSR. It always returns 0 when read.

0 (B_0x0): Writing 0 has no effect.

1 (B_0x1): Writing 1 triggers a rising edge event on event x. This bit is auto cleared by hardware.

SWI50

Software interrupt on event x When EXTI_SECCFGR.SECx is disabled, SWIx can be accessed with non-secure and secure access. When EXTI_SECCFGR.SECx is enabled, SWIx can only be accessed with secure access. Non-secure write to this SWI x is discarded, non-secure read returns 0. When EXTI_PRIVCFGR.PRIVx is disabled, SWIx can be accessed with unprivileged and privileged access. When EXTI_PRIVCFGR.PRIVx is enabled, SWIx can only be accessed with privileged access. Unprivileged write to this SWIx is discarded, unprivileged read returns 0. A software interrupt is generated independent from the setting in EXTI_RTSR and EXTI_FTSR. It always returns 0 when read.

0 (B_0x0): Writing 0 has no effect.
