Signal Name:
JTDI
Signal Description:
IEEE 1149.1 Test Data Input
Signal Type:
Input
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 tied to ground for the
DS21FF44/DS21FT44.
Signal Name:
JTDO
Signal Description:
IEEE 1149.1 Test Data Output
Signal Type:
Output
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 tied to ground for the
DS21FF44/DS21FT44.
