This example program shows how to configure timer/counter 1 as an 8-bit timer. An interrupt service routine (ISR) is invoked each time the timer overflows (goes from 0xFF to 0x00). Inside the ISR, the overflow_count variable increments. To test this prog

由于时钟源可以自由选择,因此,此类Timer一般均与Event Counter(事件计数器)合在一起。 2、IO口:任何MCU都具有一定数量的IO口,没有IO口,MCU就失去了与外部沟通的渠道。根据IO口的可配置情况,可以分为如下几种类型: 纯输入或纯输出口:此类IO口由MCU硬件设计决定,只能是输入或输出,不可用软件来进行实时的设定。

Zero appears in the 'out' section.At counter 0, there is an output being sent. Here is a single digit number, "1" that signifies the word "out".The output is sent by counter 1. There is a value of 2 present, written as "Out".The output is once again sent by counter 2. ...
