Functional Description
2.4.2 Chip Reset
Power down and power on are controlled by the P_ON pin. A low at this pin keeps the
IC in Power Down Mode. All voltage regulators and the internal biasing are switched off.
A high at the P_ON pin activates the appropriate voltage regulators and the internal
biasing of the chip. A power up reset is generated at the same time.
