What is the difference between EXTI PR1 and EXTI PR2 registers

[MOB1]

Hi,

I want to know the difference between EXTI PR1 and EXTI PR2 registers in stm32wb55xx.

[AScha.3]

in RM is register description, what you want more ??

I mean I know that it is pending register but why it is named like PR1 and PR2?

In stm32f series there is only one PR register not PR1 and PR2 what is the difference

In the 'WBxx there are more interrupt sources than 32, so their control is split to two sets of registers (it's not just the PR register).

As AScha.3 said, this should be fairly obvious by reading the relevant chapter in RM.
