Using the circuit in Fig 1, a 68HC11 µP's stop instruction can put the µP's external RC-oscillator clock, as well as the µP itself, into a low-power mode. On receiving an interrupt, the µP will exit the stop condition and enable the RC clock. The RC clock, being a low-Q circuit, will start up immediately. Crystal oscillators, on the other hand, can waste precious milliseconds coming up to speed and stabilizing.

The software can load every program in the internal EEPROM (68HC11A1 and 68HC11811) and execute it step by step. The board must be in BOOTSTRAP-MODE.

Figure 2 shows a block diagram for this sine-wave generator. You can easily analyze the generator's behavior by writing state equations in the z domain. You can also write equations in the s domain. The location of the two poles on the right-hand side reveals the generator's oscillatory nature. The inverse Laplace transformation is simple and results in a sine-wave statement.

This algorithm uses steps in the form of n/m, where n is an integer multiplier that is not a power of 2 and m is an integer that is a number with a power of 2. Making n and m relatively independent allows you to accurately set the number of samples in one cycle. When n is larger than 255, multiplying by n using 8-bit is time consuming. This algorithm allows n to be as high as 215 and the results to be as high as 231. Division by m is easy and fast because you simply left shift the register value. The overall operating principle is to keep these values as integers to avoid using floating-point arithmetic. The resultant assembler routine is simple and fast.

With the HC11 board you will see all the advantages of the MC68HC11. The control of any LCD, a menustructure, the saving of data in the internal EEPROM, the application of SPI and SCI and many more. You will learn these and more using this card.
