Notes
a. Conditions are 5.0V, 25 ^oC, 3 MHz.
b. Conditions are without Crystal Oscillator, V_cc = 3.3 V, -40 ^oC <=TA <= 85 ^oC.
c. Conditions are V_cc = 3.3 V, -40 ^oC <= TA <= 85 ^oC. Correct operation assumes a properly loaded, 1 uW maximum drive level, 32.768 kHz crystal.
d. Trimmed for appropriate V_cc.
e. Ideal values are +/- 5% absolute tolerance and +/- 1% tolerance relative to each other (for adjacent levels).
