Syntax:

• SXOR

Description:

SXOR pops the top and next-to-top levels of the stack, performs the logical XOR operation on the popped values, and pushes the result back onto the stack:

Stack before SXOR:

High Bank	Low Bank
A	B	Top
C	D	Next 1
E	F	Next 2

Stack after SXOR:

High Bank	Low Bank
A^C	B^D	Top
E	F	Next

Note: A, B, C, D, E, F denote TRUE or FALSE.

Microcode Pattern:

Takes 1 cycles to execute.

Exceptions :

No exceptions.

Example :

IPUSHEQ 255 3 0xa 0xb !! Pushes on both banks of the stack integer 
                      !! condition for equality

IPUSHEQ 255 3 0xc 0xd !! Pushes on both banks of the stack integer 
                      !! condition for equality

SXOR                  !! Performs the SXOR operation 
                      !! as described above
