Posted on August 19, 2005 at 08:52what is the purpose of the BUSY bit in the PCU_PWRCR register ?
currently when going to sleep I am setting the FLASH-LP and LPVRWFI bits.
I then wait for BUSY to go to 0 before entering LPWFI mode.
Does this need to be done, or is the BUSY bit only used for other situations ?
Also how long should this take, sometimes it appears to take for several seconds.
many thanks
Ben
