Hi Everybody,
I am Sreedhar, i am a new member of this group. I am reading sharc 21266
hardware reference manual.
I am reading serial ports chapter. In the data word format section.
it is given as when DIFS = 1 and SPTRAN = 1
If a Frame sync occurs when a transmitter FIFO is empty, the MSB or the LSB
of the previous word is transmitted.
Does this activity cause any wastage of space.
regards,
Sreedhar

Hello Sreedhar, In a way, yes - you'll be transmitting all 1's or all 0's depending on which bit is chosen and what it was for that entire frame. That should be ok though for most systems, there's no data being transmitted anyway. But if things are critical, then keeping the FIFO full is probably a really important task! Patience, persistence, truth, Dr. mike |
