Z8530_FLUSH_FIFO(9)                     Internal Functions                    Z8530_FLUSH_FIFO(9)



NAME
       z8530_flush_fifo - Flush on chip RX FIFO

SYNOPSIS
       void z8530_flush_fifo(struct z8530_channel * c);

ARGUMENTS
       c
           Channel to flush

DESCRIPTION
       Flush the receive FIFO. There is no specific option for this, we blindly read bytes and
       discard them. Reading when there is no data is harmless. The 8530 has a 4 byte FIFO, the
       85230 has 8 bytes.

       All locking is handled for the caller. On return data may still be present if it arrived
       during the flush.
