Description
FIFO buffer acts as parallel in/parallel out converter for all serial data
stream inputs and outputs
6
immediately clears the internal FIFO buffer’s read and write pointer
and ErrorReg register’s BufferOvfl bit
reading this bit always returns 0
indicates the number of bytes stored in the FIFO buffer
writing to the FIFODataReg register increments and reading
decrements the FIFOLevel value
