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:
IFCC Condition
DBNE D, label
SUBD #1
LBNE label
DBNE A, label
DECA
LBNE label
DBNE B, label
DECB
LBNE label
DBNE X, label
