Question FTDI FT2232H time setting issue


Hello,

I used FTDI FT2232H in MPSSE mode, running it at 30MHz(maximum speed) clock rate and Latency Timer is 255,

I have downloaded libraries from below link and compiled with my App. code:

http://www.ftdichip.com/Support/Soft...SPI_source.zip

I observe that the output signals show Read and Write transactions taking more times to complete 1 read or write transactions.almost 3ms

On the code side the transactions take maximum 500us.

So, Is there any setting inside FTDI chip to decrease these timing delays or Do I need to choose another drivers ?

Regards

Jaymin D
