PW-A7400
PW-A7400の回路解析の結果をまとめた
基板には"PW-A7200series"とあるので、他の2世代機種と同じかと思いきやI2C周りのハードウェア構成が3世代機種のPW-SH1に近いことがわかった。
他2世代機種との差分
DUARTがLCDコネクタ付近のPWM0 PWM1が出ていたチップ抵抗が無くなり、SH-1と同じくAUART0_RTS AUART0_CTSから出力

(RXにPCからシリアル通信を入力すればLinuxのコンソールへ入力できるが、WinCEのときにCPUのピン出力と衝突するので注意)
I2C1にMPUが接続されている
プルアップ抵抗x2が追加された

EEPROMがI2C0に接続されている

(べちょってなっているのがWriteProtectionのジャンパと思われる)
PW-SH1と同様に起動時のブート先を記録していると思われる
WriteProtectionがハンダジャンパされているので分解なしでは書き換えはできないかも (軽く調べた感じ)
