Parameters

The function’s parameters, which can only be set in IP Toolbench (see “Step 1:

Parameterize” on page 2–5), include the following settings:

■ Interface Settings

■ Parity Settings

■ FIFO Buffer Settings

■ Address & Packet Available Settings

Interface Settings

FIFO Buffer & Clock Selector Options

The following interface ‘B’ FIFO buffer and clock selector options are available:

■ A Clock (No FIFO buffer)—only available if the ‘B’ interface is an Atlantic master,

and the ‘B’ interface bus width ≥ the ‘A’ interface bus width. The relevant ‘B’

interface does not use an internal FIFO buffer, and is clocked by the ‘A’ interface

clock pin. This is recommended only if you connect ‘B’ interfaces directly to

another MegaCore function with an Atlantic slave interface

■ A Clock—the corresponding ‘B’ interface uses an internal single clock FIFO buffer,

and is clocked by the A interface clock pin
