Accessing IAP routines on P89V66x

All 8051 based microcontrollers from NXP come with some sort of built-in flash memory. The microcontrollers provide multiple methods to program the flash. The most common method is In-System Programming (ISP). In ISP, the code is transfered to the flash, through the serial port, by a built-in ISP bootloader. The other method is In-Application Programming (IAP). In IAP, the user application receives the code through whatever mechanism (like say SPI or I2C) and programs the flash. A set of built-in routines, called the IAP routines, are available to the application for manipulating the flash.

How To Determine Stack Utilization

It is necessary to know the stack utilization levels when software is developed for systems requiring high reliability. A simple technique to determine the stack utilization of a program is watermarking. In this technique the stack is filled with a pattern, and the program is executed. When the stack is used the pattern is overwritten. When the program terminates the point from which the pattern is undisturbed tells us the stack utilization level.
