4.2 Systems Instructions

Systems instructions deal with such functions as:
  1. Verification of pointer parameters (refer to Chapter 6):

  2. Addressing descriptor tables (refer to Chapter 5):

  3. Multitasking (refer to Chapter 7):

  4. Coprocessing and Multiprocessing (refer to Chapter 11):

  5. Input and Output (refer to Chapter 8):

  6. Interrupt control (refer to Chapter 9):

  7. Debugging (refer to Chapter 12):

  8. TLB testing (refer to Chapter 10):

  9. System Control:
The instructions SMSW and LMSW are provided for compatibility with the 80286 processor. 80386 programs access the MSW in CR0 via variants of the MOV instruction. HLT stops the processor until receipt of an INTR or RESET signal.

In addition to the chapters cited above, detailed information about each of these instructions can be found in the instruction reference chapter, Chapter 17
