Description
0:15 X_COUNT R W Undefined Number of iterations (minus 1) of the 'X loop'
(X_COUNT+1 is the number of single transfers in a 1D
transfer). This field is an unsigned number in the range
[0, 65535], representing 1 through 65536 iterations.
For the 'memory copy' descriptor type, (X_COUNT + 1)
is the number of transferred Bytes. For the 'scatter'
descriptor type, ceiling(X_COUNT/2) is the number of
(address, write data) initialization pairs processed.
