大家好，
我需要对两个旧的MCU进行编程：P89C52X2BN和P89C52RD2。
据我了解，P89C52RD2 支持通过串口进行 ISP 通信。但是不知道如何激活 ISP/IAP 协议？
P89C52X2BN芯片该如何刷机？它需要并行程序员吗？如果需要，请说明协议以及如何激活闪光灯模式？
我主要想找到这两款芯片（特别是 X2BN）的官方编程文档，以便参考正确的闪存编程接口和时序。如果您有数据手册中的编程部分或相关链接，请分享。
谢谢！
Hello
由此给您带来的不便，我深表歉意。P89C52 系列产品已停产，因此不再提供支持，有关该系列产品的信息也已不再提供。
如果这对您有用，以下是 89C51 的相关信息；重要提示：我无法确认或测试这些信息是否适用于 89C52。
89C51Rx+/Rx2/66x 微控制器的在线编程和应用内编程
顺祝商祺！
