The move-to-SR, STLDSR, and RTE instructions include an optional PST = 0x3 value, indicating an entry
into user mode. Additionally, if the execution of a RTE instruction returns the processor to emulator mode,
a multiple-cycle status of 0xD is signaled.
Similar to the exception processing mode, the stopped state (PST = 0xE) and the halted state (PST = 0xF)
display this status throughout the entire time the ColdFire processor is in the given mode.
