Direct

The direct addressing mode is used to address operands in the direct page of the memory (location $0000 to $00FF).

Example:

             XDEF Entry
  MyData:    SECTION
  data:      DS.B 1
  MyCode:    SECTION
  Entry:
  main:      LDA #$55
  STA data 
             BRA main
  

In this example, the value $55 is stored in the variable data. The opcode generated for the instruction STA data is two bytes long.
