• Manufacturer Part Number: dsp56000
• Description: 24-bit Digital Signal Processor Family Manual
• Manufacturer: Freescale Semiconductor, Inc

Operation:
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:
Explanation of Example: The execution of the RESET instruction resets all on-chip
peripherals and the interrupt priority register (IPR).
Condition Codes:
The condition codes are not affected by this instruction
