基本指令域 | 位数 | 域描述 |
[SPINUP] | 20 | 每个基本指令前被加有一系列用于标签定时的逻辑零(0)。标签的同步电路使用消息的该部分建立读取/解码消息的板载定时和随后对阅读器应答的定时。 |
[SOF] | 1 | 帧开始标识符。逻辑一(1) |
[CMD] | 8 | 8位域指定了发送到标签的指令。(参考以下指令数据表)。8位最多产生256种指令。其中的四个用于类型I标签并且预留剩余地址空间用于多个改进的类别II及更高的标签。 |
[P1] | 1 | [CMD]域数据的奇数奇偶校验 |
[PTR] | 7 | 7位-标签地址位置的指针。值在LSB开始并逐步建立。在试图与[VALUE]域中规定的数据相匹配时,[PTR]是标签的开始点。 |
[P2] | 1 | [PTR]域数据的奇数奇偶校验 |
[LEN] | 7 | 7位-等于[VALUE]域中发送数据的长度。 |
[P3] | 1 | [LEN]域数据的奇数奇偶校验 |
[VALUE] | 可变(1-96) | 对于类别I标签为1到96位数据。根据Ping,滚动,休眠,或删除指令,这是标签试图与其自身地址相匹配的数据。(LSB首先) |
[P4] | 1 | [VALUE]域数据的奇数奇偶校验 |
[P5] | 1 | 全部奇偶校验域的奇数奇偶校验 |
[EOF] | 1 | 帧结束标识符。逻辑一(1) |
