Description: 1.将所要制作成BOOT的程序,在编译之前将其中断向量映射到3F80,
寄存器PMST的值置为3FA0.
2.在CCS中,编译该程序时,加上-v548选项,如下所示:
打开PROJECT->BUILD OPTIONS->COMPILER
-g -as -fr"D:\myprojects\dspii_g\vc5402\lcd" -v548
同时,在PROJECT->BUILD OPTIONS->LINKER中
MAP FILENAME -m
lcd/debug/lcd.map
3.进行编译:
4.编译后在产生了两个文件,一个是.MAP,一个.OUT.
5用记事本编写一个.cmd文件.-1. Will be produced by the BOOT program, prior to the compilation of its interrupt vectors mapped to the 3F80, register PMST the value of the home as 3FA0. 2. In CCS, compile the program, plus-v548 option, as shown below : Open the PROJECT-> BUILD OPTIONS-> COMPILER-g-as-fr " D: \ myprojects \ dspii_g \ vc5402 \ lcd" -v548 Meanwhile, in PROJECT-> BUILD OPTIONS-> LINKER in MAP FILENAME-m lcd/debug/lcd.map 3. compile: 4. compiled in the production of two documents, one is. MAP, 1. OUT. 5 using Notepad to write a. cmd file.

Description: c54x dsp的中断为低电平沿触发。当产生低电平时，输出给vc5402的int1引脚，每按一次，产生一个低电平脉冲。-C54x DSP interrupt for low level along the trigger. When leads to low electricity at ordinary times, vc5402 output to the int1 pin, each as a, produce a low level pulse.
