Hi all:
I want to receive a period 16ms uart data frame,
baud rate is 38400,
each frame size is 12 bytes,
In order to keep app read the in time and less time delay,
I set read fifo interrupt trigger size is 8 bytes，
however when i call read() in block mode，
and each time i read all i can read till read() blocked,
but i found that the period is not 16ms at user space,
Is there any other register i have to set to keep the data read in time and period as input?
dose dm8168 has time delay interrupt as i set 8 bytes trigger interrupt,
and another 4 bytes will receive in the next time delay interrupt,
Is this right?
best regards
xavier
