Note: The external RC oscillation frequencies shown in
above are provided for design guidance only and not tested
or guaranteed. The user needs to take into account that the
external RC oscillation frequencies generated by the same
circuit design may be not the same. Because there are vari-
ations in the resistance and capacitance due to the toler-
ance of external R and C components. The parasitic
capacitance difference due to the different wiring length
and layout may change the external RC oscillation frequen-
cies.

Note: There may be the difference between package
types(PDIP, SOP, TSSOP). The user should modify the
value of R and C components to get the proper frequency
in MC80F0704/0708/0804/0808 or one package type to
another package type.
