Syntax:

• SEX C5

Description:

The SEX instruction induces a software exception. The optional input C5 to the SEX instruction has the following function:

• C5: When C5 = 1, the exception is conditioned by the top of the stack

It should be noted that the last value of the AGU is recorded, modulo 256, as a halt code on configuration register 0x20 (see the exceptions below).

Microcode Pattern:

Takes 30 cycles to execute.
    Example: SEX 0
