Programming Language: Assembly Language

The assembly language introduces symbolic words with a one-to-one correspondence to a machine language.
The operation of the instruction can be associated with the symbol using alphabets and numbers. It is called mnemonic notation.

It is an example of a program written in the assembly language.
In the first line “LD A, 0x55”, it means that 0x55 data is LD (Load) to A register, that is, transferring.

The assembly language has different grammar and notation depending on the microcontroller.
Therefore, when using a different microcontroller, it is necessary to learn the assembly language of the new microcontroller.
