Microcontrollers Debugger Manual

frequency is always the oscillator frequency. Two radio buttons allow you to choose
between cycles or true-time display in debugger status bar.

Clearing Reset cycles/time makes the debugger accumulate cycles/time other than CPU
reset. The true-time unit is the microsecond. The TRUETIME debugger command line
command gives the time as a number in microseconds. The OSCFREQUENCY variable
displays or sets the oscillator frequency.

Bus Trace

The FCS can record all executed instructions and memory accesses in the Trace
component, up to one million frames. Enable recording in the Trace menu or context-
sensitive menu after opening the Trace component.

NOTE

Refer to the ColdFire On-Chip DBG Module manual for the Trace Component
Window common functionality and common menu entries.

By default, FCS records instructions only (faster). Check Record memory accesses and
choose Textual mode in the Trace menu or context-sensitive menu to record memory
accesses as well.
