Transmitter Operation
9-21
Synchronous Serial Port
If the SDTR is loaded with a new word while the transmit FIFO buffer is full, the
new word will be lost; the FIFO buffer will not accept any more than four words.
Continuous mode can be discontinued (changed to burst mode) only by a seri-
al-port or device reset. Changing the FSM bit during transmit or halt will not
necessarily cause a switch to burst mode.
