12 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. It is recommended to transmit an SRES
strobe after turning power on in any case. See section 27.1 on page 31 for a description of the
recommended start up sequence after turning power on.
