PWR register and wakeup from Standby mode

RN
Senior

Hello,

I want to know whether PWR_CSR resets or not when exiting the standby mode using wakeup pins. there is an ambiguity in the RM

in STM32F446RE MCU RM document @ 6.1.2 Power reset it is mentioned as below

"A power reset is generated when one of the following events occurs:

1. Power-on/power-down reset (POR/PDR reset) or brownout (BOR) reset

2. When exiting the Standby mode

A power reset sets all registers to their reset values except the Backup domain" ( so if i understood correctly wakeup from standby resets PWR_SCR)

now @ 5.4.2 PWR power control/status register (PWR_CSR) it is mentioned as below

"Reset value: 0x0000 0000 (not reset by wakeup from Standby mode)"

Please advice . Thanks
