Notes 1: This is applied when the main clock division selection bit = “0” and f(f2) = 12.5 MHz.

2: When the main clock division selection bit = “1,” the minimum value of tc = 80 ns.

3: When the main clock division selection bit = “1,” values of tw(H)/tc and tw(L)/tc must be set to values

from 0.45 through 0.55.
