5. XTAL1 is a CMOS input and RESET is a Schmitt trigger input.
6.3 A.C. Characteristics
AC specifications are a function of the particular process used to manufacture the product, the ratings
of the I/O buffers, the capacitive load, and the internal routing capacitance. Most of the specifications
can be expressed in terms of multiple input clock periods (T
CP
), and actual parts will usually
experience less than a
±
20 nS variation.

specification is used as a reference in other specifications.
3. There are no duty cycle requirements on the XTAL1 input.
