Notes
The divide-by-three and divide-by-four
circuits cannot be used.
The no-divider (1/1) option cannot be used.
Using the no-divider (1/1) option and the
3 to 6 V
recommended circuit constants. If the use of circuit
values other than the recommended values is unavoidable, the
frequencies, divider options, and VDD ranges specified for the
single-pin external clock input option must be strictly observed.
The IC cannot be driven by an external clock with this option. If external clock drive is required, select either the external
clock option or the 2-pin RC oscillator option
