32.3.1.4.1 Wake-up on Interrupt

An enabled interrupt event wakes up the device from Sleep or Idle mode and then the following occurs:

• If the assigned priority for the interrupt is less than or equal to the current CPU priority, the device wakes up and continues code execution from the instruction following the PWRSAV instruction that initiated Sleep/Idle mode.
• If the assigned priority level for the interrupt source is greater than the current CPU priority, the device wakes up and the CPU exception process begins. Code execution continues from the first instruction of the ISR.
