Measurement modes

Mode

Description

Continuous

Mode

In continuous mode, the IC continuously performs measurements. Interrupt pin is

configured as output and the interrupt functionality can be configured using interrupt

configuration registers. Interrupt persistence can be configured in a way that an

interrupt is generated after every measurement. Wait time between measurements

can be set by user.

Single-shot

Mode

In single-shot mode, the IC performs a single measurement and returns to stand-

by state. Single measurement is initiated by I2C command. Interrupt is disabled in

this mode.

Synchronous

Mode

In synchronous mode, the IC continuously performs measurements. The start of the

measurements is initiated by a negative edge of the pulse detected on the interrupt

pin. Interrupt pin is initially configured as input. After initiation of the measurements,

the interrupt pin is configured as output. Interrupt functionality can be configured

using interrupt configuration registers. Interrupt persistence can be configured in a

way that an interrupt is generated after every measurement. Wait time between

measurements can be set by user.

Synchronous

Single-shot

Mode

In synchronous single-shot mode, the IC performs a single measurement and

returns to stand-by state. The start of the single measurement is initiated by a

negative edge of the pulse detected on the interrupt pin. Interrupt pin is configured

as input. Interrupt is disabled in this mode.
