Section 2 CPU
(9)
The T bit in the status register (SR) changes according to the result of the comparison. Whether a
conditional branch is taken or not taken depends upon the T bit condition (true/false). The number
of instructions that change the T bit is kept to a minimum to improve the processing speed.
Table 2.4
(10) Immediate Data
Byte immediate data is located in an instruction code. Word or longword immediate data is not
located in instruction codes but in a memory table. The memory table is accessed by an immediate
data transfer instruction (MOV) using the PC relative addressing mode with displacement.
With the SH-2A, 17- to 28-bit immediate data can be located in an instruction code. However, for
21- to 28-bit immediate data, an OR instruction must be executed after the data is transferred to a
register.
Table 2.5
Note: @(disp, PC) accesses the immediate data.

Description
T bit is set when R0 ≥ R1.
The program branches to TRGET0
when R0 ≥ R1 and to TRGET1
when R0 < R1.
T bit is not changed by ADD.
T bit is set when R0 = 0.
The program branches if R0 = 0.
