# However DBGACK will be set only when nSRST is released.
# Furthermore, the JTAG interface doesn't respond at all when
# the CPU is in the WFI (wait for interrupts) state, so it is
# possible that initial tap examination failed. So let's
# re-examine the target again here when nSRST is asserted which
# should then succeed.
