The GetProperty command has no data phase.
Response: In response to a GetProperty command, the target will send a
GetPropertyResponse packet with the response tag set to 0xA7. The parameter count
indicates the number of parameters sent for the property values, with the first parameter
showing status code 0, followed by the property value(s). The next table shows an
example of a GetPropertyResponse packet.

14.3.8.6 SetProperty command
The SetProperty command is used to change or alter the values of the properties or
options in the Kinetis Bootloader ROM. However, the SetProperty command can only
change the value of properties that are writable—see
Table 14-57 , Properties used by
Get/SetProperty Commands. If you try to set a value for a read-only property, then the
Kinetis Bootloader will return an error.
The property tag and the new value to set are the 2 parameters required for the
SetProperty command.
