Reduction in the Active Power Consumption of FX2LP18

Version 1
    Question: How to reduce the active power consumption of FX2LP18?

     

    Answer:

    1) changing the CPUCS register bits 4 and 3 to reduce the clock speed to 12 MHz or 24 MHz

    2) changing IFCONFIG.6 to 0 to set the interface clock speed to 30 MHz if FX2LP18 is sourcing interface clock to GPIF/Slave FIFO interface. 

    3) ensuring that all unused I/Os are input only (by changing the OEx bits) 
     
    4) make sure VCC_IO is set to 1.8V.
