The Address Register points to the register currently being accessed. Since the most significant four bits of all
addresses are zero, this register contains only the six least significant bits, AR[5:0].

Notes:
1 Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the
device. These are stress ratings only. Functional operation of the device at these or any other conditions above
those indicated under the normal operating conditions section of this specification is not recommended.
Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2 The device is fabricated using high-performance CMOS technology. It should be handled as an ESD-sensitive
device. Voltage on any signal pin that exceeds the power supply voltage by more than +0.5V can induce
destructive latchup.
