基于飞思卡尔单片机xs128的串口函数，编写的printf函数可以很简单的移植到其他单片机上使用，程序源码十分简单而且有注释-Based on Freescale microcontroller serial port function xs128, prepare the printf function can be very simple to use portable to other microcontrollers, the program is very simple and ann

因为“飞思卡尔”S12单片机不支持Printf()函数，要想输出还得自己编写输出函数。所以我给大家提供一个Printp90函数吧！-Since " Freescale" S12 does not support single-chip Printf () function, in order to prepare the output will have its own output function. So everyone give me a function Printp
