Application Note

NOTE:
interact with each other. The intent of this application note is to present
a range of uses for the MC68HC05JJ/JP analog features with details on
how to set them up. It also points out some pitfalls the designer might
encounter.
This application note covers these 12 topics:
All members of the MC68HC05JJ/JP series of MCUs have the same
analog subsystem and support timers, and they all have the same
interface and control registers for these functions. Therefore, this
application note covers all these members equally. The variations
between series members are in memory type, memory size, number of
I/O (input/output) pins, and personality EPROM. The designer should
consult the individual MCU technical data book for specific information
about the features on each member.
Examples of “typical” data are given in this application note so that the
reader has an idea of the general behavior of the devices. These typical
data are taken using a few samples of the devices and do not represent
the full range of variation in the given parameter. For more information
on the range of parameters, the reader should refer to the appropriate
data sheet or consult the factory.
