Signal Name:
Signal Description:
Signal Type:
Test instructions and data are clocked into this pin on the rising edge of JTCLK. If not used, this pin
should be pulled high. This function is available when FMS = 0. FMS is connected to ground for the
DS21FF44/DS21FT44.
Signal Name:
Signal Description:
Signal Type:
Test instructions and data are clocked out of this pin on the falling edge of JTCLK. If not used, this pin
should be left unconnected. This function is available when FMS = 0. FMS is connected to ground for
the DS21FF44/DS21FT44.
