USB Superspeed Peripherals

Hello, I'm currently modifying the SRAM_FX3 project included in the SuperSpeed Explorer Kit and would like to increase the number of address lines from 8 to 13 in GPIF Designer.  I assumed that making this change would force CY_U3P_PIB_GPIF_ADDR_COUNT_LIMIT in cyfxgpif2config.h to change from 0xFF to 0x1FFF but it is not updating.  Can you tell me how CY_U3P_PIB_GPIF_ADDR_COUNT_LIMIT is calculated from the GPIF Designer file?

   

Thanks,

   

Scott

This is not an automatic process. You will need to initialize and load the counter  accordingly to your requirements. If you wan to change it to 0x1FFF, you need to modify the state machine. You need to check the LD_ADDR_COUNT action, double click and set your required limit here.
