Power-on reset cell
The power-on reset cell generates a low going pulse whenever the digital power supplies are below
their lower limits. The power-on reset signal resets the sensor internally and is also available on the
PORB pin and may be used to reset a co-processor.
The PORB cell monitors both the 3V3 and 1V8 supplies. If the 1V8 supply is not required then
PDVREG1V8 must be tied high.
