In case the delay is estimated by the user to be more than one cycle the

The user should read the results of the associated delay-line at
MPWLDECTRL#[WL_DL_ABS_OFFSET#] and in case the user estimates that the
reasonable delay may be above 1 cycle then the user should indicate it at
MPWLDECTRL#[WL_CYC_DEL#]. Moreover the user should indicate it in

is 100/256 parts of a cycle, but the user estimates that the delay is above 2 cycles
then MPWLDECTRL#[WL_CYC_DEL#] should be configured to 2, so the total
delay will be 2 and 100/256 parts of a cycle
Probably it would just possible to not overwrite the mdmisc register in
