JTAG Interface
JTAG Interface
The BCM88335 supports the IEEE 1149.1 JTAG boundary scan standard for performing device package and
PCB assembly testing during manufacturing. In addition, the JTAG interface allows Broadcom to assist
customers by using proprietary debug and characterization test tools during board bring-up. Therefore, it is
highly recommended to provide access to the JTAG pins by means of test points or a header on all PCB designs.
See Table 21: “BCM88335 GPIO/SDIO Alternative Signal Functions,” on page 85 for JTAG pin assignments.
