By following this flow, the e300 core remains in low power state while the rest of the system is operational,

and does not get out of this state as a result of any interrupt or time-based event.

2. Clear PMCCR[SLPEN] and disable the core time base unit by clearing SPCR[TBEN]. See

3. The e300 core enters low power state by accessing the HID0 register.

4. Set ACR[COREDIS] in the system arbiter register with an external master (that is, PCI). This

Section 5.3.2.4, “System Priority and Configuration Register (SPCR),”

steers all device interrupts to the PCI_INTA so the core cannot receive any interrupt requests.

MPC8313E PowerQUICC™ II Pro Integrated Processor Family Reference Manual, Rev. 2

Make sure that the core cannot receive any interrupt requests during the time

interval between setting HID0 and setting ACR[COREDIS]. This can be

achieved if the rest of the system is idle (during the initialization).
