Does it use a Slow Clock to turn off Main Clock?

Hello, everyone:

In Arm's SSE-200 subsystem, 

• MAINCLKREQ is the system request for MAINCLK to become active.
• MAINCLKRDY is the notification that MAINCLK is ready to be used.

MAINCLK is turned off in hibernation mode. There is a Slow Clock in hibernation mode.

Does it use Slow Clock to launch MAINCLKREQ and capture MAINCLKRDY ?

Thank you.
