Anyway, adding delays on JTAG level should be corresponding to generating
some TCK in stable state, EVER.
We never should have to add ANY 'software' delay in the JTAG level , if we
do (and I think we do) this is the better way to get instable ISP.
the delay is typically used to wait for SRST to float back up
and the sorts. JTAG can be gated during these operations.
JTAG gated and waiting an external event ! wait-for-event
So this should be more like a JTAG_pause() command than a JTAG_sleep(us)
command.
Short delays, when possible, are better to implement as clocking out
ticks.
Yes, using TCK in a STABLE STATE.
