11. Flash Memory

Since multimedia applications are getting increasingly
demanding, it is necessary to provide additional memory
space to be used for storing more data. The flash memory module
enables the microcontroller to use additional

8Mbit

flash memory. It is

connected to the microcontroller via the Serial Peripheral Interface (

SPI

).
