Transmit FIFO Size (Partition Channel i)
These bit fields determine the channel specific partition size of the
central transmit FIFO in multiples of 4 DWORDs:
partition size i = ’TFSIZEi’ * 4 DWORDs,
range 0...124 DWORDs
Note: The entire size of all FIFO partitions must not exceed the total
Note: If the complete central transmit FIFO is assigned to only one
