Power On Reset

When the power supply complies with the requirements in Table 10 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 16.1 on page 23 for further

details.
