1T51单片机实现精确数字钟 因为普通单片机内核是12T 这里采用1T51内核的使得定时误差变得极小，同时加入补偿函数可以说定时已经达到理想精度-1T51 SCM accurate digital clock for the general microcontroller core is used here 1T51 core 12T makes timing error becomes minimal, while adding compensation function can be sai

A 1T51 core which contain 16 verilog files. this mcu core consiste with standard 51
