Result:
This example uses two words of memory and executes in two machine cycles. The call to
the subroutine FFT2 places PC+2 (1 FFDH) on the stack. All information currently on
the stack is pushed up the stack. The subroutine address is then placed in the PC register.
The processor executes the next instruction addressed by the PC, the FFT2 subroutine.
Initialization:
Instruction:
Result:
This example uses two words of memory and executes in two machine cycles. The
condition code UO is tested by the processor before executing the CALL instruction.
Because the UO bit is enabled, the CALL routine is executed exactly like the example
above. The condition code UO is input to the processor that determines if subroutine FFT2
is used. Another CALL instruction can determine if another subroutine, FFT1, is used.
