1
Function:
This test verifies the PUSHAW, PUSHW, and POP instructions.
Procedure:
The instructions are performed.
Hardware Tested:
The WE 32100 Microprocessor is tested.
Data Returned:
The failing test number (last number displayed on the system console before
failure) is returned.
Notes:
None
Test Number:
2
Function:
This test checks the unconditional jump instruction.
Procedure:
A jump instruction is performed. If the jump is not accomplished, the next
instruction indicates an error.
Hardware Tested:
The WE 32100 Microprocessor is tested.
Data Returned:
The failing test number (last number displayed on the system console before
failure) is returned.
Notes:
None
Test Number:
3
Function:
This test checks the branch to subroutine and return from subroutine
instructions.
Procedure:
A small subroutine is set up that, after entered, returns on a conditional value
of zero.
Hardware Tested:
The WE 32100 Microprocessor is returned.
Data Returned:
The failing test number (last number displayed on the system console before
failure) is returned.
Notes:
None
Test Number:
4
Function:
This test checks the jump to subroutine and return from subroutine
instructions.
Procedure:
A small subroutine is set up that, after entered, returns on a conditional value
of zero.
Hardware Tested:
The WE 32100 Microprocessor is returned.
Data Returned:
The failing test number (last number displayed on the system console before
failure) is returned.
Notes:
This test is similar to Test 3 except that it exercises the jump instruction rather
than the branch to subroutine instruction.
It
also uses a different return
condition.
