■
NO — When GO command is issued, the trace data will be stored in trace
memory starting at the next trace memory location. All previously stored trace
data will not be overwritten. All newly captured trace data will be stored
starting at the next trace memory location.
Acquire Trace on GO (TRCAQU)
Use the TRCAQU parameter to control the acquiring of trace data to the trace
memory on a
GO command. The trace data will also be acquired when stepping,
running to a PC value, or running back to a calling function. The trace acquire
settings
OFF and ON determine when the trace memory will acquire trace data on
a
GO command as follows:
■
OFF — When a GO command is issued, no trace data will be acquired and
saved in the trace memory.
■
ON — When a GO command is issued, all trace data will be acquired and
saved in the trace memory.
AMCC 440GX Processor Only:
Trace Output Source (TRCSRC)
Use the TRCSRC parameter to determine the source of trace output. Trace can be
collected from the General Purpose Input/Output (
GPIO) or the External Bus
Master Interface (
EBMI.) The default is GPIO.
ColdFire Processors Only:
Emit Operands on DDATA Pins (TRCREPORT)
Use the TRCREPORT parameter to select whether or not the ColdFire processor
will emit read and write memory operands on the DDATA pins.
NO -- When a GO command is issued, the CSR register is not configured to force
the processor to emit read and write memory operands on the DDATA pins.
YES -- When a GO command is issued, the CSR register is configured to force the
processor to emit read and write memory operands on the DDATA pins. The
memory operands are captured in the trace memory and displayed in the trace as
memory cycles. When this parameter is set to
YES, you must configure the Set
Code Range (
CR) option.
