Sets the width of the AHB address bus used to interface to the
system memory.
Sets the width of the AHB data bus used to interface to the
system memory.
Sets the width of the APB data bus used to access the registers
within the core.
Defines the maximum number of frames that can reside in the

receive FIFO at one time. The maximum number of frames
that reside in the RX FIFO at one time is 2 RCDEPTH -1.
Sets the size of the internal FIFO used to buffer transmit data.
The size is 2 TFIFODEPTH × AHB_DWIDTH / 8 bytes.
The transmit FIFO size must be greater than TCDEPTH
times the maximum permitted frame size.
RFIFODEPTH
7 to 12
10
Sets the size of the internal FIFO used to buffer receive data.
The size is 2 RFIFODEPTH × AHB_DWIDTH / 8 bytes.
The receive FIFO size must be greater than RCDEPTH times
the maximum permitted frame size.
