The current 4-minute data transfer timeout is misleading and broken. Instead of such a long wait, calculate the timeout duration based on the length of the data transfer. The current formula is the transfer length in bits, divided by a multiplication of bus frequency in Hz, bus width, DDR mode and converted the mSec. The value is bounded from the bottom to 1000 mSec.
