Field Function
As the transfer control descriptor is first loaded by software, this 9-bit (ELINK = 1) or 15-bit (ELINK = 0)
field must be equal to the value in the CITER field. As the major iteration count is exhausted, the contents
of this field are reloaded into the CITER field.
NOTE: When the software loads the TCD, this field must be set equal to the corresponding CITER field;
otherwise, a configuration error is reported. As the major iteration count is exhausted, the
contents of this field is reloaded into the CITER field. If the channel is configured to execute a
single service request, the initial values of BITER and CITER should be 0x0001.
