ABSTRACT:
A FIFO unit for buffering serial communications includes a register and a unit for maintaining a single pointer. The single pointer functions as an IN pointer during writes and an OUT pointer during reads. The same circuitry maintains the pointer for both reads and writes to the FIFO. This circuitry preferably includes a single counter. If an error occurs during reading, the single pointer can be reinitialized and reading restarted, without loss of data. The register is not erased until reading is complete.
