Relative Address. The JP, JP cc, or CALL opcode includes a signed relative offset field

of 8, 12, 16, or 24 bits, which is added to the Program Counter’s contents. Table 15 pro-

vides the relative address operand ranges. For jumps within the same module, the assem-

bler uses the most efficient offset size. For relative jumps across modules, the assembler

uses a default offset size that can be configured at assembly time.

Table 15. Relative Jump Offset Ranges

Operand Bits Offset Range

8 –128 to +127

12 –2,048 to +2,047

16 –32,768 to +32,767

24 –8,388,608 to +8,388,607

1 2 ... 51 52 53 54 55 56 57 58 59 60 61 ... 215 216
