Truth Tables
Truth tables provide complementary information to the state diagram. They also clarify device
behavior and applicable restrictions when considering the actual state of the banks.
Unspecified operations and timings are illegal. To ensure proper operation after an illegal event,
the device must be powered down and then restarted using the specified initialization sequence
before normal operation can continue.
