6.3.5.1. CONTACT_GET_SET_PWR_UP_SEQUENCE
This Escape command is used to get or set the following parameters:

Smart card Power-on sequence

Delay between successive Activation retires

Enable/Disable any Voltage Class
As soon as card insertion is detected and Power ON message is received from the host, the
firmware will start Activation with the configured voltage sequence. If the Activation fails, it will
wait for the configured Activation delay and then retry with the next enabled Voltage class. If
power up succeeds at an operating voltage, the firmware will continue card communication at
that voltage. If power up fails in all the enabled operating voltages, then the firmware will report
an error.
Input:
The first byte of the input buffer will contain the escape code. The next byte shall contain the
function to be performed. Third byte shall contain the parameter for the function.
