Note 1: When the on-chip regulator is enabled, its BOR circuit will automatically trigger a device Reset
before VDD reaches a level at which full-speed operation is not possible.

Frequency
41.6667 MHz
For frequencies between 4 MHz and 41.6667 MHz, FMAX = (107.619 MHz/V) * (VDDCORE – 2V) + 4 MHz
Note 1: When the on-chip voltage regulator is disabled, VDD and VDDCORE must be maintained so that
VDDCORE ≤ VDD ≤ 3.6V.
