JTAG configuration allows an unlimited number of Cyclone IV devices to be cascaded
in a JTAG chain.

Notes to
(1) You must connect the pull-up resistor to a supply that provides an acceptable input signal for all devices in the chain.
(2) Connect the nCONFIG and MSEL pins to support a non-JTAG configuration scheme. If you only use a JTAG
(3) You must connect the nCE pin to GND or driven low for successful JTAG configuration.
(4) All I/O inputs must maintain a maximum AC voltage of 4.1 V. Signals driving into TDI, TMS, and TCK must fit the

programmability (ISP) purposes. Jam STAPL supports programming or configuration
of programmable devices and testing of electronic systems, using the IEEE 1149.1
JTAG interface. Jam STAPL is a freely licensed open standard. The Jam Player
provides an interface for manipulating the IEEE Std. 1149.1 JTAG TAP state machine.
