Posted on August 17, 2005 at 12:25In the reference manual rev. 6 on page 43 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 Standy 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,
