In command TEMPSEL (see section 9.1.72) each MTx, where x=0, 1, 2,…, E, F, has a value between 0 and 15. MTx
= 0 results in 0V increment on V0, MTx = 1 results in Mx=5mV increment, …, MTx = 15 results in Mx=15x5mV=75mV
increment. Note that each MTx individually corresponds to a temperature interval; The relations between Mx and V0
quantity due to temperature V0(T) are described in the equations shown as follows:
