Analog Temperature Sensor

The characteristics of the analog temperature sensor at 3.0 V supply voltage are listed in Table 10

below. 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

When the power supply complies with the requirements in Table 12 below, proper Power-On-Reset

functionality is guaranteed. Otherwise, the chip should be assumed to have unknown state until

transmitting an SRES strobe over the SPI interface. See Section 19.1 on page 42 for further details.
