Ready Busy Timeout Counter 
When the FRB pin is placed in a busy state, the values 
of the bits RBTMOUT[19:0] in FLBSYTMR are copied to 
these bits. These bits are counted down while the FRB 
pin is busy. A timeout error occurs when these bits are 
decremented to 0.

  Data FIFO Register (FLDTFIFO) 
FLDTFIFO is used to read or write the data FIFO area. 
In DMA transfer, this register must be specified as the destination or source. 
Note that the direction of read or write specified by the SELRW bit in FLCMDCR must match 
that specified in this register. When changing the read/write direction, FLDTFIFO should be 
cleared by setting the AC0CLR bit in FLINTDMACR before use.

Data FIFO Area Read/Write Data 
In write: Data in this register is written to the data FIFO 
area. 
In read: Data read from the data FIFO area is stored in 
this register.
