Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.
2: Other conditions: FRC = 7.37 MHz, TUN<5:0> = b'011111 (for Min), TUN<5:0> = b'100000 (for Max).
This parameter depends on the FRC accuracy (see Table 25-19) and the value of the FRC Oscillator
Tuning register (see Register 9-4). For complete details on calculating the Minimum and Maximum time
see Section 5.3 “Programming Operations”.
3: These parameters are assured by design, but are not characterized or tested in manufacturing.
