      Im working with a cmos sensor connected to the slave fifo of 68013, the frame sync signal of the cmos is captured by INT0. In the INT0 service routine, i want to insert some user defined bytes to the cmos data stream. My question is, how can i exactly know how many bytes are in the fifo now? Because the inserted bytes should not overwrite any cmos data that are already in the fifo. Can the EPxBCH:L register or Autopointer be helpful?

         

      Thanks!
