1.3.2.2. 外部ホストを使用したEMRのアンロード
JTAGポートなどの外部ホストを使用してEMRの内容をアンロードするには、SHIFT_EDERROR_REG JTAG命令を使用します。このJTAG命令は、TDIピンとTDOピンの間のエラー検出ブロックのJTAGピンにEMRを接続します。CRC_ERRORがHighになればいつでもこの命令を実行することができます。
EMRの内容は、このレジスターが次のCRCエラー情報によって上書きされる前にアンロードする必要があります。
次の例は、EMRの内容をアンロードするSHIFT_EDERROR_REG JTAG命令の実行に使用される.jam™ STAPL (Standard Test and Programming Language) 形式ファイル (Jam) を示しています。
