(1) Parameters are derived using the histogram method.
(2) The external reference voltage is selected by: SREF2 = 0 or 1, SREF1 = 1, SREF0 = 0. dVREF = V
R+ – V
R–, V
R+ < AVCC, V
R– > AVSS. Unless otherwise mentioned, dVREF > 1.5 V. Impedance of the external reference voltage R < 100 Ω, and two decoupling capacitors, 10 µF and 100 nF, should be connected to VREF+ and VREF- to decouple the dynamic current. Also see the
MSP430F5xx and MSP430F6xx Family User's Guide.
(3) Parameters are derived using a best fit curve.
