Operational Description
3.1
General Information
3.1.1
Configuration After Reset
The proceeding after hardware reset is shown in figure 15.
The DSP program must be downloaded to the external memory of the ISAR V1.0. As further ISAR
versions will not require the program download, the ISAR version should be checked first before the
download mechanism is started.
After download is finished, an automatic selftest is started for memory errors and to check if the
clocks from the IOM-2 interface are present. The result of this selftest should be requested by the
host.
Before configuration for data transmission/reception is done, the version number of the DSP software
should be verified to check which functionality is available.
