The datasheet and register map description shows two different formulas to calculate the INSTCAL_DLY value.
Datasheet Page 26:
INSTCAL_DLY = tDLY × fOSC (in MHz)/ 2CAL_CLK_DIV. tDLY
For Pin 3 capacitance between 0.47uF and 4.7uF,
tDLY = 2.5 μs × C/(0.47 μF)
In the Register Map document (snau251a.pdf) Page 8,
INSTCAL_DLY = T x fOSCIN / (2CAL_CLK_DIV).
T = 2.5 x CBIASVCO / 4.7 μF.
CBIASVCO is the bypass capacitor at pin 3.
On the datasheet there is multiply by tDLY at the end and a divide by 0.47uF.
But the Register map formula does not have the second multiply by tDLY and the division factor is 4.7uF.
Can somebody tell me which one is the correct formula?
