*1 fOSC is the frequency of the internal master clock (the master clock is the frequency generated by
multiplying the original oscillation clock by 2).
*2 If this device is used in circumstances where the ambient temperature (Ta) exceeds 85°C, be sure to
contact your local Oki sales office in advance.
