Section 2 CPU
Table 2.7
Immediate Data: Byte immediate data is placed inside the instruction code. Word and longword
immediate data is not placed inside the instruction code, but in a table in memory. The table in
memory is referenced with an immediate data transfer instruction (MOV) using PC-relative
addressing mode with displacement.
Table 2.8
Note: Immediate data is referenced by @(disp,PC).
Absolute Addresses: When data is referenced by an absolute address, the absolute address value
is placed in a table in memory beforehand. Using the method whereby immediate data is loaded
when an instruction is executed, this value is transferred to a register and the data is referenced
using register indirect addressing mode.

Description
If R0 ≥ R1, the T bit is set.
A branch is made to TRGET0
if R0 ≥ R1, or to TRGET1 if R0 < R1.
The T bit is not set by ADD.
If R0 = 0, the T bit is set.
A branch is made if R0 = 0.
