Self-test is used to troubleshoot the memory management circuits. The system
exe.
r ciser does not test the MM circuits directly. They are tested when the
system exerciser is run on the memory. Enter TEST A to run self-test. Enter

to see the results.
A code of 0000.0001 next to the MM mnemonic indicates no errors detected
with the memory management circuits. Replace the system module if any
other code is listed.
Appendix E contains the power-up and self-test error codes.
2.9 TEST 9 - FP - Floating Point
The floating point (FP) controls the arithmetic operations done for the CPU.
Self-test is used to lroubleshoot the floating point circuils. The system
exerciser does not test the FP circuits. Enter TEST 9 to run self-test. Enter
TEST SO to see the results.
A code of 0000.0001 next to the FP mnemonic indicates no errors detected
with the floating point circuits. Replace the system module if any other code
is listed.
Appendix E contains the power-up and self-test error codes.
2.10 TEST 8 - IT- Interval Timer
The interval timer (IT) controls key timing operations in the system.
Self-test is used to troubleshoot the interval timer circuits. The system
exerciser does not test the IT circuits. Enter TEST 8 to run self-test. Enter
TEST SO to see the results.
A code of 0000.0001 next to the IT mnemonic indicates no errors detected
with the interval timer circuits. Replace the system module if any other code
is listed.
Appendix E contains the power-up and self-test error codes.
