Syntax:

• HALT

Description:

The HALT instruction stops run-mode execution and raises a HALT exception for one cycle. 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: HALT

Exceptions :

Configuration Register: 0x20 (CrMemExc)

[0]	00000000 00000001	RO	HALT	Raised only for one cycle
[39:32]	000000FF 00000000	RW	Halt Code	By HALT & SEX (even if masked)

Example :

AGU_ED ZERO 0x0000000A
HALT
     !! Halts run-mode execution
     !! with a halt code of 0xA
