Question
Do I need to wire the PST signals to the debug connector on my ColdFire V2/3/4 target if I want to determine if the device is running or halted?
 
Answer
PEmicro has updated its ColdFire software products so that they no longer require use of the processor status (PST) pins on the debug connector. These pins are traditionally used to determine if the part is running in user mode or halted in debug mode. The default is still to use the PST pins for status, but this can be optionally disabled in the connection assistant. When disabled, the software will use the BDM communications pins to determine the processor status. This results in a slight slowdown in communication and download rates, but the advantage is that the target board no longer has to wire the PST signals to the debug connectors. This also alleviates some problems in the case where the customer application needs to make use of the alternate functions of the processor status pins instead of using them for debug.
