90 / 104 page  12.1.7 T_AH_QVAR_SENSITIVITY_L (B6h) and T_AH_QVAR_SENSITIVITY_H (B7h) Temperature / analog hub /Qvar sensor sensitivity value register (R/W) This sensitivity value is also applied to the data processed in the finite state machine (FSM) and machine learning core (MLC) blocks. This register corresponds to the conversion value of the embedded temperature (or analog hub / Qvar) sensor. The register value is expressed as half-precision floating-point format: SEEEEEFFFFFFFFFF (S: 1 sign bit; E: 5 exponent bits; F: 10 fraction bits). By default it contains the sensitivity of the temperature sensor; when the analog hub / Qvar is enabled, the user needs to modify the sensitivity accordingly. The default value of T_AH_QVAR_S_[15:0] is 0x19D1 (when using the embedded temperature sensor, this value corresponds to 0.045 °C/LSB with 12-bit resolution). Table 232.
