| SWI22 | Software interrupt on line 22 A software interrupt is generated independently from the setting in EXTI_RTSR and EXTI_FTSR. This bit always returns 0 when read. This bit is automatically cleared by hardware. 0 (B_0x0): Writing 0 has no effect. 1 (B_0x1): Writing 1 to this bit triggers an event on line 22. |
