This program memory addressing logic is handled by a register referred to as a program counter . 程序存储器的导址逻辑是由寄存器来实现的，这个寄存器叫程序计数器。
If we load this known address, as data, into the program counter, we execute a jump instruction . 如果我们将已知的地址依数据加载到程序计数器中，就可以执行一条转移指令。
Some applications require that the counter perform both functions, count up as well as count down . 在某些应用中，要求计数器能同时完成两种功能，既能累加计数，又能累减计数。
The counter has been preset to 0000 and as the input "runs," the counter advances by 1 bit per input pulse . 计数器预置0000，并在时钟输入下计算每输入一个脉冲计数器便累加10。
There are nevertheless some advantages in using a quenching circuit even with a self-quenching counter . 尽管如此，即使在使用自猝灭计数器时，配合使用猝灭线路还是有一些好处的。
The counter output, which represents a binary number, decreases by 1 any time the counter is triggered by a pulse . 每当计数器被时钟脉冲触发一次时，计数器输出的二进制数便累减1。
The channel counter and decoder provide the channel select information to the data latch and transmit logic circuits . 通道计数器和解码器向数据锁存和传送逻辑电路提供通道选择信息。
The maximum count of a combination counter is thus a function of the number of stages of the binary and feedback counters . 组合计数器的最大数值是二进制计数器和反馈计数器的级数的函数。
The counter has the ability to switch from one mode to the other without altering the number contained in the counter . 这种计数器能从一种方式转换为另一种方式，但计数器中的数字保持不变。
Their response is more closely related to the number of ionizing particles entering the tube than to the energy absorbed . 它们的响应与进入计数器的致电粒子数目的关系，比响应与吸收的能量的关系更加密切。
