MPU Subsystem Basic Programming Model
4.4.3.3
MPU Out of Standby Mode
The MPU out of standby mode uses the following sequence of operation and applies to initial power-up
and wakeup from device off mode.
1. The PRCM must start clocks through DPLL programming.
2. Detect active clocking through status output of DPLL
3. Initiate an interrupt through the INTC to wake up the ARM core from STANDBYWFI mode.
4.4.3.4
MPU Power-On From a Powered-Off State
1. DPLL Power On, MPU Power On, NEON Power On, Core Power On (INTC) should follow the ordered
sequence per power switch daisy chain to minimize the peaking of current during power-up.
NOTE:
The core domain must be on, and reset, with the clocks of the DPLL on, before the MPU
can be reset.
2. Next, follow the reset sequence as described in
, Basic Power-On Reset.
