Section 3 DSP Operating Unit
The rule is shown in table 3.3.
Table 3.3
Note: The terms used above in table 3.3, are defined as follows.
Repeat Control Instructions and Repeat Control Macros: To describe a repeat loop, the RS
and RE registers must be specified appropriately by the LDRS and LDRS instructions and then the
number of repetitions must be specified by the SERTC instruction. An 8-bit immediate data or a
general register can be used as an operand of the SETRC instruction. To specify the RC as a value
greater than 256, use SETRC Rm type instructions.
Table 3.4
The RS and RE registers must be specified appropriately according to the rules shown in table 3.3.
The SH assembler supports control macros (REPEAT) as shown in table 3.5 to solve problems.

RS register
Calculates (disp x 2 + PC) and stores the result to the
RE register
Sets 8-bit immediate data imm to the RC[11:0] bits of
the SR register and sets the information related to the
number of repetitions to the RF[1:0] bits of the SR.
RC[11:0] can be specified as 0 to 255.
Sets the[11:0] bits of the Rm register to the RC[11:0]
bits of the SR register and sets the information related
to the number of repetitions to the RF[1:0] bits of the
SR.
RC[11:0] can be specified as 0 to 4095.
