Hardware Standby Mode @ write operation RTC

In the reference manual rev. 7 on page 48 i see the following restrictions.

Since any write operation to the Real Time Clock registers requires at least two 32 kHz clock cycles to complete, if software configures the RTC registers, Standby mode can only be entered after the write operation to the RTC register is over. This can be monitored by polling the RTOFF bit in the RTC_CRL register.

When i use the Software Standby Entry, i can polling the RTOFF.

But, i can nothing doing, when i use the Hardware Standby Entry.

Can a Hardware Standby Entry during write operation to the RTC cause any problems?

thanks,
