Operation modes
M48T02, M48T12
The state of the eight three-state data I/O signals is controlled by E and G. If the outputs are
activated before tAVQV, the data lines will be driven to an indeterminate state until tAVQV. If
the address inputs are changed while E and G remain active, output data will remain valid
for output data hold time (tAXQX) but will go indeterminate until the next address access.
