 We are using the following micro controller from ST Micro.
            MCU Series STM32F4
            MCU Line STM32F407/417
            MCU name STM32F407ZETx
            MCU Package LQFP144
            MCU Pin number 144
 
    We are using FSMC interface to access a communication ASIC whichrequires synchronous bus.
 
    We are using the following configuration:
        NOR Flash/PSRAM/SRAM/ROM 1
        Chip select: NE4
        Memory type: PSRAM
        Address: 16 bits
        Data: 16 bits
        Clock: Burst Read Write
        Wait: Synchronous
 
        NOR/PSRAM control:
            Memory type PSRAM
            Bank Bank 1 NOR/PSRAM 4
            Write operation Enabled *
            Wait signal polarity Low polarity
            NOR/PSRAM timing:
            Bus turn around time in HCLK clock cycles 15
            CLK clock divide ratio 16
            Data latency in CLK clock cycles 2

Kindly let us know how do we get started with the reading and writing of the device.
