//  デバイスにアクセスするためのメソッドをenum bodyに記述する
//    mmdPbs,mmdPbz,mmdPws,mmdPwz,mmdPls  ピーク

//    4文字目  P=ピーク,R=リード,W=ライト

//    6文字目  s=符号拡張,z=ゼロ拡張
//  ピークとリードの返却値の型はmmdPbsとmmdRbsだけbyte、他はint
//  ピークはSRAMスイッチの読み取りやデバッガなどで使用する
//  ピークはMPUやデバイスの状態を変化させず、例外もスローしない
//  リードとライトはMPUやDMAによる通常のアクセスで使用する
//  リードとライトはバスエラーをスローする場合がある
//  アドレスの未使用ビットはデバイスに渡る前にすべてクリアされていなければならない
//    バスエラーは未使用ビットがクリアされたアドレスで通知されることになる
//  異なるデバイスに跨るアクセスはデバイスに渡る前に分割されていなければならない
//  奇数アドレスに対するワードアクセスはデバイスに渡る前に分割または排除されていなければならない
//  4の倍数でないアドレスに対するロングアクセスはデバイスに渡る前に分割または排除されていなければならない
//  デバイスのメソッドを直接呼び出すときはアドレスのマスクや分割を忘れないこと
