Motorola 24-Bit Digital Signal Processor, DSP56000 manual Reset On-Chip Peripheral Devices

INSTRUCTION DESCRIPTIONS

	RESET	Reset On-Chip Peripheral Devices		RESET
Operation:			Assembler Syntax:
	Reset the interrupt priority register		RESET
	and all on-chip peripherals

Description: Reset the interrupt priority register and all on-chip peripherals. This is a software reset which is NOT equivalent to a hardware reset since only on-chip peripher- als and the interrupt structure are affected. The processor state is not affected, and exe- cution continues with the next instruction. All interrupt sources are disabled except for the trace, stack error, NMI, illegal instruction, and hardware reset interrupts.

Restrictions: A RESET instruction cannot be the last instruction in a DO loop (at LA).

Example:

:
RESET	;reset all on-chip peripherals and IPR
:

Explanation of Example: The execution of the RESET instruction resets all on-chip peripherals and the interrupt priority register (IPR).
