For wake-up from STOP the basic flow is as follows:
Freescale Semiconductor
1.

4.
5.
6.
Analog die detects a wake-up condition, e.g. on a switch input or start bit of a LIN message.
Analog die exits Voltage Regulator low power mode.
Analog die asserts the interrupt signal D2DINT.
CPU starts clock generation.
CPU enters interrupt handler routine.
CPU services interrupt and acknowledges the source on the analog die.
CLI
STOP
Entering STOP mode mode with D2DSWAI asserted the clock will complete the high duty
cycle portion and settle at low level.
; re-enable right before the STOP instruction
; stack and turn off all clocks inc. interface clock
