3.14.1 Power Supply Sequencing
The GS4911B/GS4910B has a recommended power supply sequence. To ensure
correct power-up, the ANALOG_VDD and CORE_VDD power pins should be
powered before IO_VDD.
Device pins may be driven prior to power-up without causing damage.
3.15 Device Reset
In order to initialize operating conditions to their default states, the application layer
must hold the RESET signal LOW during power up and for a minimum of 500us
after the last supply has reached its operating voltage.
