(d) Items Displayed in the [EVA AUD Trace] Window
Table 3.15 Items Displayed in the [EVA AUD Trace] Window
Column Contents
PTR Pointer offset within the trace buffer in ascending order, with the position where
tracing stopped as 0 (signed decimal)
Address Address value
Type Indicator of type of traced information
BRANCH: Branch instruction
BRANCH (LOST): Indicates that trace information was lost at or before this
branch instruction.
MEMORY: Memory access
MEMORY (LOST): Indicates that trace information was lost at or before this
access to memory.
MEMORY (OVF): Access to memory was within 128 clock cycles after the
output of trace information from the MCU. Some results of tracing that
correspond to an instruction-execution information trace for the previous 128
clock cycles are not present. In certain cases, there will be no corresponding
instruction-execution information trace.
MEMORY (LOST) (OVF): Indicates that trace information was lost at or before
this access to memory. Furthermore, access to memory was within 128 clock
cycles after the output of trace information from the MCU. Some results of
tracing that correspond to an instruction-execution information trace for the
previous 128 clock cycles are not present. In certain cases, there will be no
corresponding instruction-execution information trace.
INSTRUCTION: Instruction-execution information
BranchType Indicator of type of branch
GENERAL: General branch
GENERAL (DLY): Delayed general branch
SUBROUTINE: Subroutine branch
SUBROUTINE (DLY): Delayed subroutine branch
EXCEPTION: Branch due to an exception
EXCEPTION (DLY): Delayed branch due to an exception
Master Indicator of bus master that generated the trace event
CPU: CPU was the bus master
DMAC (A-DMAC): DMA or A-DMA was the bus master
