o:
The software sequence is clocked with E controlled READs.
p:
Once the software controlled STORE or RECALL cycle is initiated, it completes automatically, ignoring all inputs.
q:
Note that STORE cycles (but not RECALL) are inhibited by VCC < VSWITCH (STORE inhibit).
r:
An automatic RECALL also takes place at power up, starting when VCC exceeds VSWITCH and takes tRESTORE. VCC must not drop below
VSWITCH once it has been exceeded for the RECALL to function properly.
s:
Noise on the E pin may trigger multiple READ cycles from the same address and abort the address sequence.
t:
If the Chip Enable Pulse Width is less than ta(E) (see Read Cycle) but greater than or equal tw(E)SR, than the data may not be valid at
the end of the low pulse, however the STORE or RECALL will still be initiated.
