Protocol Parameters
Figure 3–4 on page 3–12 shows the Protocol Parameters tab.
Figure 3–4. Receiver Protocol Parameters
Select Real-Time Programmable , so most of the protocol parameters on this tab
become input pins to the MegaCore function. These input pins allow each parameter
to be connected to a user-implemented register, and controlled at run-time.
Select Fixed Value , to enter values for the protocol parameters on this tab.
IP Toolbench then fixes these values in the MegaCore function, making the
parameters static and the input pins unavailable.
Calendar Options
Turn on Asymmetric Port Support (only available if you select the Real-time
programmable ) for the calendar to allow asymmetric weighting of calendar entries to
control the allocation of bandwidth to a given SPI-4.2 port. You must program the
calendar for the MegaCore function to produce the status channel (refer to
A port with twice the calendar entries of all other ports nominally uses twice as much
bandwidth on the SPI-4.2 interface depending on the data characteristics. Ports can be
disabled by removing them from the calendar.
