31.4.4. Read and Write Burst Count Fields
The programmable read and write burst counts are only available when using the extended descriptor format. The programmable burst count is optional and can be disabled in the read and write hosts. Because the programmable burst count is an eight bit field for each host, the maximum that you can program burst counts of 1 to 128. Programming a value of zero or anything larger than 128 bits will be converted to the maximum burst count specified for each host automatically.
The maximum programmable burst count is 128 but when you instantiate the mSGDMA IP, you can have different selections up to 1024. Refer to the MAX_BURST_COUNT parameter in the parameter table. You will still have a burst count of 128 if you program for greater than 128. Programing to 0, gets the maximum burst count selected during instantiation time.
