Initial value
Initial value
0 : FRAME access
1 : DMA slave interface access
Select the method of accessing the transmit buffers and receive buffers. The initial value is frame access.
0 : 16-bit data width
1 : 8-bit data width
Select the data bus width for the transmit buffers and receive buffers. The initial value is the 16-bit data width.
If the 8-bit data width is used, fix D15 to D8 at either “1” or “0”.
