WFE control register 2 (WFE_CR2)

Address offset: 0x01

Reset value: 0x00

Bit 1 TIM2_EV1: TIM2 event 1

0: TIM2 capture and compare interrupt sources generate external interrupts.

1: TIM2 capture and compare interrupt sources logically ORed and configured to generate WFE

events (no interrupt serviced).

This bit is written by software.

Bit 0 TIM2_EV0: TIM2 event 0

0: TIM2 update, trigger and break interrupt sources generate external interrupts.

1: TIM2 update, trigger and break interrupt sources logically ORed and configured to generate WFE

events (no interrupt serviced).

This bit is written by software.
