Features

to the system design These are Power-Save control Dynamic RAM refresh and an asynchronous Numerics Coprocessor interface (80C186XL only) The 80C186XL oscillator circuit is designed to be used either with a parallel resonant fundamental or third-overtone mode crystal depending upon the frequency range of the application This is used as the time base for the 80C186XL The output of the oscillator is not directly available outside the 80C186XL The recommended crystal configuration is shown in Figure 2b When used in third-overtone mode the tank circuit is recommended for stable operation Alternate.
