These parameters are characterized but not tested

† Data in "Typ" column is at 5.0V, 25

°C unless otherwise stated. These parameters are for design guidance only and are not tested.

Note 1: Measurements are taken in RC Mode where CLKOUT output is 4 x TOSC

Note: All tests must be do with speciﬁed capacitance loads (Figure 13-1) 50 pF on I/O pins and CLKOUT
