0x1: Module is managed automatically by HW according to clock domain transition. A clock domain sleep transition put module into idle. A wakeup domain transition put it back into function. If CLKTRCTRL=3, any OCP access to module is always granted. Module clocks may be gated according to the clock domain state. |
