@LB()

Return low byte.

@lb(byte_string)

Remarks

The @lb(byte_string) directive returns the lower byte of a word address.

This directive applies to the DSP56800E processor, supported only for operands of this form:

  X:xxxx/X:xxxxx/#xxxx

Example

  move.b  X:@lb(byte_string), r0 ;loads first byte of 
  byte_string

Additionally, when the C source specifies:

  char a;
  char b; 
  //there is no gap between variables a and b

use XREF to declare variables and use @LB to access the char variables from assembly:

move.w   #23,A
move.bp   A1,X:@lb(Fa)
move.w    #78,A
move.bp   A1,X:@lb(Fb)
