Freescale-Recommended BDM Pinout
MCF5271 Reference Manual, Rev. 2
Freescale Semiconductor
30-45
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.
