M24SR64-Y System file & RF ON/OFF status & Pin-Dis

Dear All :

目的 : 專案需求,M24SR64-Y 在 Vcc 無提供電壓時( Pin-Dis = Low ),CR95HF 不能讀 UID,

          控制器將 Pin-Dis 拉 High 時,才可使外部 CR95HF 讀取 UID。

問題 1. M24SR64-Y no power (Pin-Disable = Low),CR95HF read UID;

            M24SR64-Y power on (Pin-Disable = High),CR95HF no read UID;

            目前測試結果,狀態相反,請問是否可以透過修改 System file 達到目的嗎?

            【 參考 datasheet page 25. Table 10 , ( bit 3 : RF disable pad is at low state / high state )】。

Thanks All.#
