Figure 11-2:
Flash memory module connection schematic
Since multimedia applications are
getting increasingly demanding, it is
necessary to provide additional memory
space to be used for storing more data.
The ash memory module enables the
microcontroller to use additional 8Mbit
ash memory. It is connected to the
microcontroller via the Serial Peripheral
Interface (SPI).
