Function
TRSTB
Input
5
Active low Test Reset (TRSTB). This signal
provides an asynchronous QDSX test access
port reset via the IEEE P1149.1 test access port.
TRSTB is a Schmitt triggered input with an
integral pull up resistor. When not being used,
TRSTB should be tied to RSTB.

Pad Ring Power Pins (VDDO[6:1]). These pins
must be connected to a common well decoupled
+5V DC power supply together with the
VDDI[3:1], TAVD[4:1], and RAVD[4:1] pins. Care
must be taken to avoid coupling noise between
these pins.
