3.19 Trace Functions
The E10A emulator has two branch-instruction trace functions.
(1) Internal Trace Function
The branch source and branch destination addresses, mnemonics, operands, and source lines are
displayed. Since this function uses the trace buffer built into the MCU, a realtime trace can be
acquired.
Notes: 1. The number of branch instructions that can be acquired by a trace differs according to
the product. For the number that can be specified for each product, refer to the online
help.
2. The internal trace function is not supported for all products. For the specifications of
each product, refer to the section related to the trace functions in section 6, SHxxxx
E10A Emulator Specifications, or to the online help.
3. The internal trace function is not extended for all products. For the specifications of
each product, refer to the section related to the trace functions in section 6, SHxxxx
E10A Emulator Specifications, or to the online help.
(2) AUD Trace Function
This is the large-capacity trace function that is enabled when the AUD pin is connected to the
emulator. This function displays the branch source and branch destination addresses, mnemonics,
operands, and source lines.
When the branch source and branch destination instructions are one branch, the number of branch
instructions acquired by a trace is a maximum of 4,096 in the PCMCIA-type emulator and a
maximum of 16,384 in the PCI-type emulator.
Table 3.4 shows the AUD trace function.
Notes: 1. The AUD trace function is not supported for all products. For the specifications of
each product, refer to the section related to the trace functions in section 6, SHxxxx
E10A Emulator Specifications, or to the online help.
2. The AUD trace function is not extended for all products. For the specifications of each
product or the number of acquired branches, refer to the section related to the trace
functions in section 6, SHxxxx E10A Emulator Specifications, or to the online help.
