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.
