RM0440 Rev 4 457/2126
RM0440 Extended interrupts and events controller (EXTI)
460
Note: The configurable wakeup lines are edge-triggered. No glitch must be generated on these
lines. If a rising edge on a configurable interrupt line occurs during a write operation to the
EXTI_RTSR register, the pending bit is not set.
Rising and falling edge triggers can be set for the same interrupt line. In this case, both
generate a trigger condition.
Bits 31:10 Reserved, must be kept at reset value.
Bits 9:8 RTx: Rising trigger event configuration bit of line x (x = 40 to 41)
0: Rising trigger disabled (for Event and Interrupt) for input line
1: Rising trigger enabled (for Event and Interrupt) for input line
Bits 7:2 Reserved, must be kept at reset value.
Bits 1:0 RTx: Rising trigger event configuration bit of line x (x = 32 to 33)
0: Rising trigger disabled (for Event and Interrupt) for input line
1: Rising trigger enabled (for Event and Interrupt) for input line
