7. Instruction Set
T Bit: The T bit in the status register (SR) is used to show the result of a compare operation, and
is referenced by a conditional branch instruction. An example of the use of a conditional branch
instruction is shown below.
ADD #1, R0
CMP/EQ R1, R0 ; If R0 = R1, T bit is set to 1
BT TARGET
In an RTE delay slot, status register (SR) bits are referenced as follows. In instruction access, the
MD bit is used before modification, and in data access, the MD bit is accessed after modification.
The other bits—S, T, M, Q, FD, BL, and RB—after modification are used for delay slot
instruction execution. The STC and STC.L SR instructions access all SR bits after modification.
Constant Values: An 8-bit constant value can be specified by the instruction code and an
immediate value. 16-bit and 32-bit constant values can be defined as literal constant values in
memory, and can be referenced by a PC-relative load instruction.
MOV.W @(disp, PC), Rn
MOV.L
There are no PC-relative load instructions for floating-point operations. However, it is possible to
set 0.0 or 1.0 by using the FLDI0 or FLDI1 instruction on a single-precision floating-point
register.

; T bit is not changed by ADD operation
; Branches to TARGET if T bit = 1 (R0 = R1)
