The emulator pins are multiplexed with other pins. When the emulator is connected, function 1
cannot be used because the emulator uses the pins that TCK, TMS, TDI, TDO, _TRST, and
_ASEBRKAK/_ASEBRK have been multiplexed. Function 1 can be used when the pins that
AUD has been multiplexed are not connected to the emulator.
When the multiplexed pins are used as the AUD functions, set the AUD pins to be used from
[AUD pin select] of the [Configuration] dialog box. The multiplexed pins are fixed to be used
as the AUD function.
When debugging is performed with the EV-chip unit connected, the AUD function is available
regardless of settings of the AUD pins above.
Note: When R5F70834A, R5F70835A, R5F70844A, R5F70845A, R5F70854A, R5F70855A,
R5F70865A, R5E71464R, R5F71464R, R5F71494R, R5F71491R, R5F71250,
R5F71251, R5F71252, R5F71253, R5F71240, R5F71241, R5F71242, or R5F71243 is
used and debugging is performed without connecting the EV-chip unit, the AUD trace
function is not available. Since the AUD trace is not output, the conditions of the AUD
Eventpoint function are not satisfied. It is also impossible to use the AUD performance
measurement, code coverage, and realtime profiling functions. These functions are
available when the emulator is connected to the EV-chip unit.
