15.3.1

EXT_FORMAT (00h)

AH / Qvar / external sensor data format (2-byte or 3-byte) for the finite state machine and machine learning core

(R/W)

Table 422. EXT_FORMAT register

0(1)

EXT_FORMAT

_SEL

0(1)

1. This bit must be set to 0 for the correct operation of the device.

Table 423. EXT_FORMAT register description

EXT_FORMAT_SEL

Selects the format of AH / Qvar / external sensor data for FSM and MLC processing. Default value: 0

(0: 2-byte format; 1: 3-byte format)

15.3.2

EXT_3BYTE_SENSITIVITY_L (02h) and EXT_3BYTE_SENSITIVITY_H (03h)

External sensor (3-byte output data) sensitivity value register for the finite state machine and machine learning

core (R/W)

This register corresponds to the conversion value of the external sensor having 3-byte output data. The register

value is expressed as half-precision floating-point format: SEEEEEFFFFFFFFFF (S: 1 sign bit; E: 5 exponent bits;

F: 10 fraction bits).

The default value of EXT_3BYTE_S_[15:0] is 0x0C00 (when using an external pressure sensor this value

corresponds to 2.441e-04 hPa/LSB).
