14 JTAG INFORMATION
The DS33R11 contains two JTAG ports. Port 1 is for the Ethernet Mapper, and Port 2 is for the T1/E1/J1
Transceiver. Because of this, this device requires special consideration during JTAG test design. For more
information on performing JTAG testing using this device, go to www.maxim-ic.com/support.
The device supports the standard instruction codes SAMPLE:PRELOAD, BYPASS, and EXTEST. Optional public
instructions included are HIGHZ, CLAMP, and IDCODE. See
required by IEEE 1149.1 Standard Test Access Port and Boundary Scan Architecture.
The Test Access Port has the necessary interface pins: JTRST, JTCLK, JTMS, JTDI, and JTDO. See the pin
descriptions for details. Refer to IEEE 1149.1-1990, IEEE 1149.1a-1993, and IEEE 1149.1b-1994 for details about
the Boundary Scan Architecture and the Test Access Port.
