2.1 CPU Register Tests
This section describes CPU register tests routines. The test harness control file ‘main.c’ provides examples of the API
for each of the CPU register tests using “C” language.
These modules test the fundamental aspects of the CPU operation. Each of the API functions has a return value in order
to indicate the result of a test.
Each of the test modules saves the original contents of the register(s) under test and restores the contents on completion.
The following CPU registers are tested:
• Working registers and Accumulator: AX, HL, DE, BC in Register Banks 0 – 3

• Stack Pointer (SP)
Figure 3 Stack Pointer Configuration
• Processor Status Word (PSW)
