NOTES: 1. The

internal
buffer
operational
amplifier,
if
switched
to
terminal
P6.4/UCB0CLK/UCA0STE/A4/CA6/Veref+/Vref+ (REFOUT = 1), must be limited; the reference buffer may become unstable,
otherwise.
2. The condition is that the error in a conversion started after tREFON or tRefBuf is less than 0.5 LSB.
3. Calculated using the box method: ((MAX(VREF(T)) -- MIN(VREF(T))) / MIN(VREF(T)) / (TMAX -- TMIN)
