(1)
Tools accessing the Spy-Bi-Wire interface need to wait for the maximum tSBW,En time after pulling the TEST/SBWCLK pin high before
applying the first SBWCLK clock edge.
(2)
fTCK may be restricted to meet the timing requirements of the module selected.
JTAG Fuse
(1)
over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)
PARAMETER

(1)
Once the fuse is blown, no further access to the JTAG/Test, Spy-Bi-Wire, and emulation feature is possible, and JTAG is switched to
bypass mode.
