Running The High-Performance Embedded Workshop; Setting Up The Emulator - Renesas SH-4A User Manual

6.2 Running the High-performance Embedded Workshop

To run the High-performance Embedded Workshop, refer to section 4.1, System Check.

6.3 Setting up the Emulator

The clocks which are used for data communications must be set up on the emulator before the
program is downloaded.
• AUD clock
A clock used in acquiring AUD traces.
If its frequency is set too low, complete data may not be acquired during realtime tracing.
Set the frequency not to exceed the upper limit for the MPU's AUD clock.
The AUD clock is only needed for using emulators that have an AUD trace function.
• JTAG (H-UDI) clock (TCK)
A communication clock used except for acquiring AUD trace.
If its frequency is set too low, the speed of downloading will be lowered.
Set the frequency not to exceed the upper limit for the MPU's guaranteed TCK range.
For details of the limitations on both clocks, refer to section 2.2.2, Notes on Using the JTAG (H-
UDI) Clock (TCK) and AUD Clock (AUDCK), in the additional document, Supplementary
Information on Using the SHxxxx. The following is a description of the procedure used to set the
clocks.
