Functional description
The PSRAM and Flash memory components have separate power supplies but share the
same grounds. They are distinguished by three Chip Enable inputs: E
memory and E1
Recommended operating conditions do not allow more than one device to be active at a
time. The most common example is simultaneous read operations in the Flash memory and
the PSRAM which would result in a data bus contention. Therefore it is recommended to put
the other device in the high impedance state when reading the selected device.
