75 / 84 page ![]() GS1661 HD/SD SDI Receiver Data Sheet 53751 - 3 September 2012 75 of 84 Legend: R = Read only ROCW = Read Only, Clear on Write R/W = Read or Write W = Write only 4.20 JTAG Test Operation When the JTAG/HOST pin of the GS1661 is set HIGH, the host interface port is configured for JTAG test operation. In this mode, pins E7, F8, F7, and E8 become TDO, TCK, TMS, and TDI. In addition, the RESET_TRST pin operates as the test reset pin. Boundary scan testing using the JTAG interface is enabled in this mode. There are two ways in which JTAG can be used: 1. As a stand-alone JTAG interface to be used at in-circuit ATE (Automatic Test Equipment) during PCB assembly. 2. Under control of a host processor for applications such as system power on self tests. When the JTAG tests are applied by ATE, care must be taken to disable any other devices driving the digital I/O pins. If the tests are to be applied only at ATE, this can be accomplished with tri-state buffers used in conjunction with the JTAG/HOST input signal. This is shown in Figure 4-32.
