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