Freescale Semiconductor
— Completely reset the device via the RESET mode.
If the outputs of the system I/Os need to be forced to a high impedance state upon entering this mode, the
PDO bit of the ME_SAFE_MC register should be set. The input levels remain unchanged.
8.4.2.4
TEST mode
The device enters this mode on the following events:
•
From the DRUN mode when the TARGET_MODE bit field of the ME_MCTL register is written
with 0001
As soon as any of the above events has occurred, a TEST mode transition request is generated. The mode
configuration information for this mode is provided by the ME_TEST_MC register. Except for the main
voltage regulator, all resources of the system are configurable in this mode. The system clock to the whole
system can be stopped by programming the SYSCLK bit field to 1111, and in this case, the only way to
exit this mode is via a device reset.
This mode is intended to be used by software to execute on-chip test routines.
NOTE
As flash modules can be configured to a low-power or power-down state in
these modes, software must ensure that the code will execute from RAM
before it changes to this mode.
8.4.2.5
RUN0…3 modes
The device enters one of these modes on the following events:
•
From the DRUN another RUN0…3 mode when the TARGET_MODE bit field of the ME_MCTL
register is written with 0100…0111
•
From the HALT mode by an interrupt event
•
From the STOP mode by an interrupt or wakeup event
As soon as any of the above events occur, a RUN0…3 mode transition request is generated. The mode
configuration information for these modes is provided by ME_RUN0…3_MC registers. In these modes,
the flashes, all clock sources, and the system clock configuration can be controlled by software as required.
These modes are intended to be used by software to execute application routines.
NOTE
As flash modules can be configured to a low-power or power-down state in
these modes, software must ensure that the code will execute from RAM
before it changes to this mode.
8.4.2.6
HALT mode
The device enters this mode on the following events:
•
From one of the RUN0…3 modes when the TARGET_MODE bit field of the ME_MCTL register
is written with 1000.
