JTAG mode signal establishing appropriate
TAP state transitions for target ISP devices
sharing the same data stream.
JTAG Test Clock. This pin is the clock
signal for JTAG operations and should be
connected to the TCK pin on all target ISP
devices sharing the same data stream.
JTAG Test Data Out. This pin is the serial
