	Heater is currently enabled.
#define	HTU31D_DIAG_TEMP_LOW_ERR   BIT(1)
	Temperature below minimum.
#define	HTU31D_DIAG_TEMP_HIGH_ERR   BIT(2)
	Temperature above maximum.
#define	HTU31D_DIAG_TEMP_OVER_ERR   BIT(3)
	Temperature under/over-run.
#define	HTU31D_DIAG_HUMI_LOW_ERR   BIT(4)
	Humidity below minimum.
#define	HTU31D_DIAG_HUMI_HIGH_ERR   BIT(5)
	Humidity above maximum.
#define	HTU31D_DIAG_HUMI_OVER_ERR   BIT(6)
	Humidity under/over-run.
#define	HTU31D_DIAG_NVM_ERR   BIT(7)
	NVM checksum error.

Functions
int	htu31d_heater_set (const struct device *dev, bool enable)
	Enable or disable the on-chip heater.
int	htu31d_read_diagnostics (const struct device *dev, uint8_t *diag)
	Read the sensor diagnostics register.
int	htu31d_read_serial (const struct device *dev, uint32_t *serial)
	Read the factory-programmed 24-bit serial number.

Detailed Description

Header file for extended sensor API of HTU31D sensor.

This exposes APIs for the on-chip heater, diagnostics register, and factory-programmed serial number, which are outside the scope of the generic Zephyr sensor driver abstraction.
