how to halt m8xx?

Hi,

I found that in m8xx the halt function is the same as the restart function because m8xx_halt() just calls m8xx_restart() in m8xx_setup.c. If I just want to halt the m8xx system but not to restart it automatically, what should I do? Set a few registers and wait for ever? THanks for your thoughts.

Regards,

- Shawn.

How about power down mode? From the 8xx manual:
"Power down mode can be used for:
	- A software initiated controlled shutdown, with optional automatic wakeup,
	- (...) "

Isn't what you want?
Check page 14-24.
