Notes:
- Pins LOCK_N and SCE are test pins for factory testing. They must be connected to VSS in
normal operation to prevent accidental enabling of a test mode.
- Output READY is set high when a measurement cycle is completed and the results in the output
registers are valid. It is cleared by reading data from address 0122h.
- CLK allows to monitor the internal clock or to apply an external clock.
- Output MISO is only activated when CS_N is low. It is in high impedance state otherwise, this
allows for parallel operation of multiple ICs.
- CS_N is active low and activates data transmission. If only a single device is used, CS_N may
remain low for several commands, for example while reading the output registers.
