CNTC: a positive going pulse clears the NTC high temperature limit and clear the STATUS[NTC] bit. The bit shall be Low
to resume NTC normal operation.

NOTE:
TOUTDIS1 & TOUTDIS2: these two bits are used to disconnect the Time Out function when B7 and B6 are High:
TOUTDIS1 & TOUTDIS2: B7 or B6 = 0 --> the Time Out function is active and operate normally.
TOUTDIS1 & TOUTDIS2: B7 = B6 = 1 --> the Time Out function is de-activated
