PARAMETER
Power-up ramp-up time
(1) When the power supply complies with the requirements shown here, proper power-on-reset functionality is assured. Otherwise, the chip
should be assumed to have unknown state until it transmits an SRES strobe over the SPI interface. See Power-On Startup Sequence
for further details.
