Table 5-1336 shows a table lookup method for translating code to temperature from temperature monitors which correspond to the temperature measured read from the WKUP_VTM_TMPSENS_STAT_j[9-0] DATA_OUT bitfields. Table 5-1336 also provides the values for the temperatures coded in WKUP_VTM_MISC_CTRL2[25-16] MAXT_OUTRG_ALERT_THR0 and WKUP_VTM_MISC_CTRL2[9-0] MAXT_OUTRG_ALERT_THR thresholds.

Table 5-1337 shows a table that gives coefficients of polynomial to calculate code or temperture. The equation to calculate code or temperature is:
y = a4 × x4 + a3 × x3 + a2 × x2 + a1 × x + a0
Function | Unit | Coefficient | ||||
a4 | a3 | a2 | a1 | a0 | ||
