The FiFO_DATA Register is used to read or write data to the internal FIFO. It can be accessed as a 16-bit
register or as a 32-bit register. Any long write to the register will put the four bytes written into the FIFO.
Any word write will put the two bytes written into the FIFO. Any long read will read four bytes from the
FIFO. Any word read will read two bytes from the FIFO.
23.5.2.3.3
See
the bit fields.
FIFO_FILL is a read-only register. Any read to it returns the current number of halfwords present in the
FIFO.
23.5.2.4
See
of the bit fields.
