10.)The procedure SPIFLASH Init( remaps and configures the pins for the SPI Interface and then configures the SPI communications with the SPIFLASH Configure SPI() procedure. How many pins are needed for the SPl interface (not including power and ground)? What is the SPI clock frequency in this library? Note that this is also assuming a 40 MHz peripheral bus clock. After initialization you will need three SPIFLASH Library procedures-SPIFLASH EraseAll() to erase the flash memory before storing new values, SPIFLASH ProgramPage to copy a buffer of data within the MCU memory to the flash, and SPIPLASH Read) to read back the data from the flash. What data type does the SPIFLASH ProgramPage () function receive and what is the maximum number of bytes that can be written per function call
