Certain exits from power managed modes do not
invoke the OST at all. There are two cases:
• PRI_IDLE mode where the primary clock source
• the primary clock source is not any of the LP, XT,

In these instances, the primary clock source either
does not require an oscillator start-up delay, since it is
already running (PRI_IDLE), or normally does not
require an oscillator start-up delay (RC, EC and INTIO
Oscillator modes). However, a fixed delay of interval
