WebJul 9, 2024 · A NOP instruction can be inserted by using inline assembly. Here's how: The simplest method using the Keil compiler is to use the intrinsic function _nop_ (). Add an #include statement in the C file to include the header file INTRINS.H (#include 'intrins.h'). This header file contains prototypes for the intrinsic library functions. http://c.biancheng.net/view/1986.html

WebMar 24, 2013 · 11. This is a header that declares a bunch of "intrinsics" -- functions that are built into the compiler so it can emit inline code for them. If you're using VC++ as the compiler, it should be in the same directory with its other standard headers. If you're using a different compiler, you'll need to change the intrinsics to suit the compiler ...
