INTERRUPT AND EXCEPTION HANDLING
Interrupt 0—Divide Error Exception (#DE)
Exception Class Fault.
Description
Indicates the divisor operand for a DIV or IDIV instruction is 0 or that the result cannot be repre-
sented in the number of bits specified for the destination operand.
Exception Error Code
None.
Saved Instruction Pointer
Saved contents of CS and EIP registers point to the instruction that generated the exception.
Program State Change
A program-state change does not accompany the divide error, because the exception occurs
before the faulting instruction is executed.
