Issue Description
When transfer size is less than fifosize, driver sets the trigger level to be same as transfer size, as shown below.

if (transBytes <= object->fifoSize)

{ /* Transaction fits entirely in FIFO */ object->rxTrigLvl = transBytes; object->txTrigLvl = transBytes; }

else
{

This is incorrect because application provided trigger level could be even less transfer size and this cause mismatch between trigger level and DMA transfer size.

Workaround
