Figure 3-95. Wake-up Basic Programming Model
A power domain A can have a functional dependency on a power domain B. Thus, when power domain A
wakes up, it may be necessary to wake up power domain B. This wake-up dependency is hardcoded for
the CORE power domain, but is programmable for the other power domains through the
PM_WKDEP_<domain> register.
