Analog Temperature Sensor
Tc = 25
°C, VDD = 3.0 V if nothing else is stated. Note that it is necessary to write 0xBF to the PTEST register to use the
analog temperature sensor in the IDLE state.

Power on Reset
For proper Power-On-Reset functionality, the power supply must comply with the requirements in
Table 10 below. Otherwise, the chip should be assumed to have unknown state until transmitting
an SRES strobe over the SPI interface. See section 16.1 on page 31 for a description of the
recommended start up sequence after turning power on.
