Bits 31:21 Reserved, must be kept at reset value.
Bit 20 SWI20: Software rising edge event trigger on line 20
(1)
.
Setting this bit by software triggers a rising edge event on the corresponding line, resulting in
an interrupt, independently of EXTI_RTSR1 and EXTI_FTSR1 settings. This bit is
automatically cleared by hardware. Reading this bit always returns 0.
0: No effect
1: Rising edge event generated on the corresponding line, followed by an interrupt
The SWI20 bit is only available in STM32G0B1xx and STM32G0C1xx. It is reserved in all
the other devices.
Bit 19 Reserved, must be kept at reset value.
Bits 18:0 SWIx: Software rising edge event trigger on line x (x = 18 to 0)
Setting of any bit by software triggers a rising edge event on the corresponding line x,
resulting in an interrupt, independently of EXTI_RTSR1 and EXTI_FTSR1 settings. The bits
are automatically cleared by HW. Reading of any bit always returns 0.
0: No effect
1: Rising edge event generated on the corresponding line, followed by an interrupt
The SW18 and SW17 bits are only available in STM32G071xx and STM32G081xx as well
as STM32G0B1xx and STM32G0C1xx. They are reserved in STM32G031xx and
STM32G041xx as well as STM32G051xx and STM32G061xx.
