Chip Reset
The chip includes a Power-On-Reset function (POR)
so when the power supplies are turned on the chip will
always power up with default values in all registers.
There are two methods to force a chip reset. The first
is to write a “1” to the RESET bit in the reset register.
This will reset the chip, and after a delay of about 10
ns, the reset bit will automatically clear itself. The
second reset method is to force the RESET pin high.
This will reset the chip until the RESET pin goes low
again. The RESET pin has an internal pull down.
