Arm pseudo Assembly command. Word

Let's talk about the role of this. Word.

 Word expression is to put a word value in the current position. This value isExpression
For example, 
_ Rwtcon:
. Word 0x15300000
Put a value at the current address, that is, _ rwtcon.Zero X 15300000

The Assembly statement translated into Intel is: 
_ Rwtcon DW 0x15300000

For example:

LDR R1, _ rwtcon

_ Rwtcon:
. Word 0x15300000
Instead of passing content from address 0x1530 0000 to R1, the content on address _ rwtcon is put to R1, and the content on address _ rwtcon is 0x15300000. Actually, we set R1 to 0x15300000.
