AVR单片机入门及C语言高效设计实践（六） ATMEAG16L的定时／计数器 ATMEAG16L有两个8位定时／计数器（T／C0、T，C2）和一个16位定时／计数器T/C1）。每一个计数器都支持PWM（脉冲宽度调制）输出功能。PWM输出在电机控制、开关电源、信号发生等领域有着广泛的应用。[第一段]-AVR C language portal and efficient design practice (6) ATMEAG16L the timer/counter All ATMEAG16L two 8 timer/counter (T/C0, T, C2) and a 16 timer/counter T/C1). Each counter support for a PWM (pulse width modulation) output function. PWM output in motor control, switching power supply, signal and other fields has wide application. [Paragraph]

用LPC93251操作nand flash K9F6408，能正确擦，写，读。改用其它芯片，方法类似，注意时序就行了。如换用大容量flash，请注意每块的页数，6408每块是16页的。-with LPC93251 operation nand flash K9F6408 can correct rub, writing and reading. Other chip switch, a similar manner, the attention on the timing of the trip. If used for large-capacity flash, to every piece of pages, 6,408 each block is the 16.
