I2C answer ready configuration (GPO field = 0xX3)

When the GPO is configured as I2C answer ready, it goes to the Low state when the

M24SR02-Y has finished to treat the I2C command and is ready to send the I2C response.

During an I2C session, after receiving a valid I2C command, GPO pin is driven low after a

delay when M24SR02-Y is ready to deliver a response on the I2C bus.

GPO is released when M24SR02-Y receives a new command.
