8253的初始化程序举例: 例1：选择2号计数器，工作在3方式，计数初值为533H（2个字节），采用二进制计数。其初始化程序段为 MOV DX，307H ；命令口 MOV AL，10110110B ；2号计数器的初始化命 令字 OUT DX，AL ；写入命令寄存器 MOV DX，306H ；2号计数器数据口 MOV AX，533H ；计数初值 OUT DX，AL ；选送低字节到2号计数器 MOV AL，AH ；取高字节送AL OUT DX，AL ；后送高字节到2号计数器 -8253 initialization procedures examples : Example 1 : Select counters on the 2nd, in three ways. Counting for the initial 533H (2 bytes), a binary counting. Initialization of its procedures for MOV DX, 307H; I ordered MOV AL, 10110110B; on the 2nd Counter initialize command word OUT DX, AL; write commands Register MOV DX, 306H; data on the 2nd Counter I MOV AX, 533H; Counting initial OUT DX, AL; low-byte sent to the 2nd Counter MOV AL, AH; With a high-byte send AL OUT DX, AL; evacuations high byte counter to the 2nd

这是LCD1602与msp430之间的通信,其实可以直接从51移植过来,但是一定要在硬件加上拉电阻,要不然是不通不过的,我说的是你用的是5V的LCD-This is the LCD1602 and communication between the MSP430 can in fact be a direct transplant from the 51, but must be coupled with pull-up resistor in the hardware, otherwise it is unreasonable, however, I say is that you use the LCD is 5V
