Timer Overview (Continued) Maximum output frequency for any timer output can be ob- tained by setting timer/register pair to zero. This then will produce an output frequency equal to (/2 the frequency of the source used for clocking the timer. Timer Registers There are four control registers that program the timers. The divide by (DIVBY) register p ...

Design Considerations (Continued) Designs using the HPC family of 16-bit high speed CMOS microcontrollers need to follow some general guidelines on usage and board layout. Floating inputs are a frequently overlooked problem. CMOS inputs have extremely high impedance and, if left open, can float to any voltage. You should thus tie unused inputs to V ...

Code Efficiency One of the most important criteria of a single chip microcon- troller is code efficiency. The more efficient the code, the more features that can be put on a chip. The memory size on a chip is fixed so if code is not efficient, features may have to be sacrificed or the programmer may have to buy a larger, more expensive version of t ...
