NOTE: The cold reset command is provided for platform development, test, and

platform-specific initialization and recovery actions. The system actions of the cold reset

command are platform specific. Issuing a cold reset command could have adverse effects on

system operation, particularly if issued during run-time. Therefore, the cold reset command

should not be used unless all the side-effects for the given platform are known.

It is recognized that there are conditions where a given controller may not be able to return a

response to a cold reset request message. Therefore, though recommended, the implementation

is not required to return a response to the cold reset command. Applications should not rely

on receiving a response as verification of the completion of a cold reset command.

Warm reset command

This command is available to the MC.

This command directs the responder's device to reset communications interfaces, but current

configurations of interrupt enables, thresholds, and so on are left alone. A warm reset does not

initiate the self test. The intent of the warm reset command is to provide a mechanism for cleaning

up the internal state of the device and its communication interfaces. A warm reset resets

communication state information such as sequence number and retry tracking, but does not reset

interface configuration information such as addresses, enables, and so on. An application may

try a warm reset if it determines a non-responsive communication interface, but it must also be

capable of handling the side effects.

Get self test results command

This command is available to MC, ChMC, and PSMC.

This command directs the device to return its self test results, if any. A device implementing a self

test normally runs that test on device power up as well as after cold reset commands. A device

is allowed to update this field during operation if it has tests that run while the device is operating.

Devices that do not implement a self test always return a 56h for this command.

While the self test only runs at particular times, the get self test results command can

be issued any time the device is in a ready for commands state.
