3.5.4
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, INTOSC,
and INTOSCIO modes). However, a fixed delay of
interval T
when leaving Sleep and Idle modes to allow the CPU
to prepare for execution. Instruction execution resumes
on the first clock cycle following this delay.
