Click button displayed with the InitFC_P, InitFC_NP, and InitFC_Cpl fields to open the
calculator and input values.
Select the checkbox Use these Data InitFC values and Use these Header InitFC values to use the InitFC
values defined in the fields when computing and interpreting offline performance summary. In
case InitFC values are not defined or 'Use these InitFC values' checkbox is not selected, the
minimum and maximum credit levels for the captured trace is automatically computed and flow
control mechanism works on the basis of those calculated values. The minimum and maximum
credit levels varies from one trace to other depending upon the size of the trace.
You can specify the Data InitFC values within the range 0 - 4095.
You can specify Header InitFC values within the range 0 - 255.
InitFC values are applicable only for Flow Control performance statistics category. You
can use InitFC values for posted, non-posted and completions transactions only when
you are computing flow control credits.
