1. ASSERT :DEF:ENDIAN_CHANGE
ASSERT is an assertion pseudo-instruction, and its syntax is: ASSERT + logical expression
def is a logical pseudo-operator, and its format is: :DEF:label, its function is to determine whether label has been defined. //*********************Additional information: if label is not defined, the compiler will report an error when compiling.
2. The four blue instructions can and can only execute one sentence, and if the first three sentences are executed, the last sentence of the post-processing program is also
b ResetHandler
3. " [ " is equivalent to if
" | " is equivalent to else
" ] " is equivalent to endif

- Learn ARM development(16)There are many things to learn about ARM, and interrupts are definitely something that needs to be learned. Since the CPU introduced interrupts, it has truly entered the multi-tasking system and greatly improved work efficiency. ...
- Learn ARM development(17)Because all embedded systems use interrupts, how does my S3C44B0 interrupt the process? Then I need to understand the whole process. To understand it in depth, the best way is to write a program ...
- Learn ARM development(18)Last time, we have learned about the interrupt handling process of ARM and how to set the interrupt function. So, does it work like this? The answer is no. Because S3C44B0 has several registers that control ...
- Embedded system debugging simulation toolAfter the embedded hardware system is designed, it needs to be debugged. Whether it is hardware debugging, software debugging or program solidification, debugging simulation tools are needed. ...
- A small question that has been bothering me recently has finally been solved~~Recently, I have not been able to understand the concept of drivers very well. Sometimes I can get a feel for it by combining some USB examples written by others, but because the ARM system does not directly explain the pins like the microcontroller ...
