8.4.3.13
Pad switch-off
If the PDO bit of the ME_
<target mode>
_MC register is 1 then
•
The outputs of the pads are forced to the high impedance state if the target mode is SAFE or TEST
This step is executed only after the
process is completed.
8.4.3.14
Clock sources switch-off
<clock source><mode>
if a given clock source
<clock source>
.
This step is executed only after
•
process is completed in order not to lose the current system clock during
mode transition.
8.4.3.15
Flash switch-off
Based on the CFLAON and DFLAON bit fields of the ME_
<current mode>
_MC and
ME_
<target mode>
_MC registers, if any of the flash modules is to be put in a low-power state, the
MC_ME requests the flash to enter the corresponding low-power state and waits for the deassertion of
flash ready status signal. The exact low-power mode status of the flash modules is updated in the S_CFLA
and S_DFLA bit fields of the ME_GS register. This step is executed only when
8.4.3.16
Main voltage regulator switch-off
Based on the MVRON bit of the ME_
<current mode>
_MC and ME_
<target mode>
_MC registers, if the
main voltage regulator is to be switched off, the MC_ME requests it to power down and clears the
availability status bit S_MVR of the ME_GS register.
This step is required only during the entry of low-power modes like HALT and STOP. This step is executed
only after completing the following processes:
