Document ID: PMC-1990267, Issue 3

The S/UNI-JET identification code is 073460CD hexadecimal.

10.23 Microprocessor Interface

The microprocessor interface block provides normal and test mode registers, and the logic

required to connect to the microprocessor interface. Normal mode registers are required for

normal operation. Test mode registers are used to enhance the testability of the S/UNI-JET.

With the exception of the S/UNI-JET Identification Register, all register descriptions can be

found in the S/UNI-JET datasheet (PMC-1990267).

The register set is accessed as described in Table 6.
