私のデバイス環境は、OSEオペレーティングシステムを実行するB4860ハードウェアチッププラットフォームで構成されており、DCSRアドレス空間マッピングタイプはSASEです。
0xf1100000 - 0xf14fffff 0x00400000 rw-r-- cio ----g- SASE dcsr
0xf1124fffから0xf1125fffの範囲内のアドレスを逆参照すると、CPUがフリーズし、ウォッチドッグタイムアウトによりリセットされました。このアドレス空間のサイズは4KBです。チップのDCSRレジスタについて知りたいのですが、DCSRレジスタの機能は何ですか？その値に直接アクセスして読み取ることはできないのでしょうか？
