3.14 JTAG Operation
When the JTAG/HOST pin is set HIGH by the application layer, the host interface
port (as described in
GSPI Host Interface on page 50
) will be configured for JTAG
test operation. In this mode, pins 16, 17, 19, and 20 become TMS, TCK, TDO, and
TDI respectively. In addition, the RESET pin will operate as the test reset pin, as
well as resetting the internal registers.
Boundary scan testing using the JTAG interface will be possible in this mode.
There are two methods in which JTAG can be used on the GS9092A:
1. As a stand-alone JTAG interface to be used at in-circuit ATE (Automatic Test
Equipment) during PCB assembly; or
2. Under control of the host for applications such as system power 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 3-17
.
Alternatively, if the test capabilities are to be used in the system, the host may still
control the JTAG/HOST input signal, but some means for tri-stating the host must
exist in order to use the interface at ATE. This is represented in
Figure 3-18
.
