I/O Buffer Drive Control
0: 1.8 V/3.3 V I/O buffer high drivability
1: 1.8 V/3.3 V I/O buffer low drivability
Power supply pin, VccQ1, can be applied 1.65 to 1.95
V or 2.7 to 3.6 V. When 1.65 to 1.95 V is applied to
VccQ1, setting the drivability high (DRV = 0) is
recommended. When 2.7 to 3.6 V is applied to
VccQ1, setting the drivability low (DRV = 1) is
recommended.
