/*****************************************************************************
SetInterruptVector:
Description:
Loads the interrupt vector table with the address of the interrupt
routine. The vector table entry number is determined by the vector
number.
Parameters:
InterProc Address of interrupt function, will be loaded into
the interrupt table.
ISR_Type Specifies if the interrupt function. Real Mode only
supports INTERRUPT_ISR (the parameter is ignored). The
parameter is kept to maintain compatibility with the
protected mode version of this function.
Returns:
None
Assumptions:
Compiler supports far and interrupt keywords
Compiler may issue a warning about IntrType not used.
IntrType is kept for protected mode compatibility.
Syntax:
SetInterruptVector(wdtISR, INTERRUPT_ISR);
Real/Protected Mode
Real Mode only
