1.3.2.2. Unloading the EMR using an External Host
To unload the contents of the EMR using an external host, such as a JTAG port, use the SHIFT_EDERROR_REG JTAG instruction. This JTAG instruction connects the EMR to the JTAG pin in the error detection block between the TDI and TDO pins. You can execute the instruction whenever the CRC_ERROR pin goes high.
You must unload the contents of the EMR before the register is overwritten by the information of the next CRC error.
The following examples show the Jam™ Standard Test and Programming Language (STAPL) Format File (.jam) used to execute the SHIFT_EDERROR_REG JTAG instruction to unload the contents of the EMR.
