12.3.66 A12403: Value Out of Range –256...255

Type: Error

Description: The offset between the current PC and label speciﬁed as the PC

relative address is not in the range of a signed 9-bit value

(smaller than –256 or bigger than 255). A 9-bit signed PC

relative offset is expected in these instructions:

• Decrement-and-branch instructions: DBEQ, DBNE

• Increment-and-branch instructions: IBEQ, INE

• Test-and-branch instructions: TBEQ, TBNE

Example:

DataSec: SECTION

var1: DS.W 1

var2: DS.W 10

CodeSec: SECTION

…

LDX #var2

label: LDD var1

CLR 1, X+

dummyBl: DCB.B 260, $A7

DBNE D, label

Tips: Replace the instruction with the following portion of code.

• For decrement and branch:
