Code Range (CR)
Use the CR parameter to set the code range. The code range must be set accurately
when the
CF TRCREPORT parameter is set to YES. The code range settings BASE
and
RANGE set the base address and the range that the code runs in.
BASE -- Any valid address from 0 to FFFFFFFE that is word aligned. Enter the
value as a hex address. (Do not enter a leading 0x before the address.)
RANGE -- any valid range that, when added to the BASE setting, is not greater than
FFFFFFFE. Enter the value as a hex address. (Do not enter a leading 0x before the
address.)
Set Work Space (WSPACE)
Use the WSPACE parameter to reserve an area of RAM to be used as a workspace.
Use the workspace to load a debug exception handler for filtered tracing. You can
also use the workspace to load a flash programming algorithm when
programming flash memory.
BASE -- Any valid address in RAM that is word aligned. Enter the value as a hex
address. (Do not enter a leading 0x before the address.)
SIZE --Any valid size that, when added to the BASE setting, is not greater than
FFFFFFFE. Enter the value as a hex address. (Do not enter a leading 0x before the
address.) The debug exception needs a
SIZE value of 400 in hex.
Set Vector Base Register on IN Command (SET_VBR)
Use the SET_VBR parameter to set the Vector Base Register (VBR) to a specified
value on an
IN command. The value should be the same as what the code will set
it to. The VBR needs to be set so that the debug exception handler address can be
entered in the exception table. The default value is zero. Bits 0..19 are not used.
3.3.2 Setting Configuration Options
There are three ways to set configuration options:
■
The Configure Trace button in the Trace view
■
The CF Options view
■
Low-level commands in the OCD Command Shell.
