Sequential Read: Sequential Reads are initiated by either a Current Address Read or a Random Address
Read. After the microcontroller receives a data word, it responds with an acknowledge. As long as the EEPROM
receives an acknowledge, it will continue to increment the data word address and serially clock out sequential
data words. When the memory address limit is reached, the data word address will “roll over” and the Sequential
Read will continue. To end the command, the microcontroller does not respond with a zero but does generate a
Stop condition in the subsequent clock cycle.

10. Power Recommendation
The device internal POR (Power-On Reset) threshold is just below the minimum operating voltage of the device.
Power shall rise monotonically from 0.0Vdc to full V_CC in less than 1ms. Hold at full V_CC for at least 100μs before
the first operation. Power shall drop from full V_CC to 0.0Vdc in less than 1ms. Power dropping to a non-zero level
and then slowly going to zero is not recommended. Power shall remain off (0.0Vdc) for 0.5s minimum. Please
consult Atmel if your power conditions do not meet the above recommendations.
