Freescale-Recommended Bdm Pinout - Freescale Semiconductor MCF5329 Reference Manual

Table 36-27. PST/DDATA Specification for Supervisor-Mode Instructions (continued)
Instruction Operand Syntax

stop #<data>
wdebug.l <ea>y
The move-to-SR 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 = 0xFF)
display this status throughout the entire time the ColdFire processor is in the given mode.
