argument. Although the command supports a stack address, at this time the call will still
take place using the current stack pointer. After execution of the function, a 32-bit return
value will be returned in the generic response message.

Response: The target (Kinetis Flashloader) will return a GenericResponse packet with a
status code either set to the return value of the function called or set to
kStatus_InvalidArgument (105).
13.3.6.2 GetProperty command
The GetProperty command is used to query the flashloader about various properties and
settings. Each supported property has a unique 32-bit tag associated with it. The tag
occupies the first parameter of the command packet. The target returns a
GetPropertyResponse packet with the property values for the property identified with the
tag in the GetProperty command.
Properties are the defined units of data that can be accessed with the GetProperty or
SetProperty commands. Properties may be read-only or read-write. All read-write
properties are 32-bit integers, so they can easily be carried in a command parameter.
