Copy of DESCR_Y_CTL of the currently active
descriptor.
[11:0] SRC_Y_INCR
Specifies increment of source address for each Y loop
iteration (in multiples of SRC_TRANSFER_SIZE). This
field is a signed number in the range [-2048, 2047].
[23:12] DST_Y_INCR
Specifies increment of destination address for each Y
loop iteration (in multiples of DST_TRANSFER_SIZE).
This field is a signed number in the range [-2048,
2047].
[31:24] Y_COUNT
Number of iterations (minus 1) of the 'Y loop'
(1)*(1) is the number of single
transfers in a 2D transfer). This field is an unsigned
number in the range [0, 255], representing 1 through
256 iterations.
For single, 1D and CRC transfer descriptor types,
descriptor will not have Y_CTL.
