3. Implementation Information
This chapter summarizes some information about the implementation of the
JTAG-Booster and describes some restrictions.
64
The JTAG-Booster currently uses the EXTEST function of the JTAG-
Interface to perform Flash programming.
The JTAG interface of the Analog Devices ADSP-21xxx does not support an
ICODE register. Therefor the analysis of the JTAG chain is not really
possible. But we try to avoid unpredictable results by comparing the length of
the boundary scan chain with the estimated length.
