摘要
介绍了串行时钟芯片ＤＳ１３０２的原理及应用，并附有ＰＬ／Ｍ９６语言简要说明其编程过程。该芯片采用三线连接，节省口线。数据的读写靠时序控制，且有写保护位，数据不易丢失，时钟准确可靠。
The principle and application of the serial time clock chip DS1302 are described. It uses 3 wire connection, simplifying the interface. With a bit of writing protection, the memory data are not easy to lose and the clock runs normally in severe environment. The program implemented in PL/M96 is detailed.
