23. Advanced User Debugger (AUD)
23.4
23.4.1
In this mode, all the modules connected to this LSI's internal or external bus can be read and
written to, allowing RAM monitoring and tuning to be carried out.
When an address is written to AUDATA externally, the data corresponding to that address is
output. If an address and data are written to AUDATA, the data is transferred to the address.
23.4.2
The AUD latches the AUDATA input when AUDSYNC is asserted. The following AUDATA
input format should be used.
