10 / 56 page Pin Description 10 September 22, 2005 IDT82V2054 QUAD E1 SHORT HAUL LINE INTERFACE UNIT TDO O High-Z 98 F13 TDO: JTAG Test Data Output This pin output the serial data of the JTAG Test. The data on TDO is clocked out of the device on the fall- ing edges of TCK. TDO is a high-Z output signal. It is active only when scanning of data is out. This pin should be left float when unused. TDI I Pull-up 99 F12 TDI: JTAG Test Data Input This pin input the serial data of the JTAG Test. The data on TDI is clocked into the device on the rising edges of TCK. This pin has an internal pull-up resistor and it can be left disconnected.
