The SH-DSP repeat (loop) control function is a special utility for controlling repetition efficiently.
The SETRC instruction is executed to hold a repeat count in the repeat counter (RC, 12 bits) and
set an execution mode in which the repeat (loop) program is repeated until the RC is 1. Upon
completion of the repeat operation, the content of the RC becomes 0.
The repeat start register (RS) holds the start address of the repeated section. The repeat end
register (RE) holds the ending address of the repeated section. (There are some exceptions. See
4.19.1 Notes.) The repeat counter (RC) holds the repeat count. The procedure for executing repeat
control is shown below:
1. Set the repeat start address in the RS register.
2. Set the repeat end address in the RE register.
3. Set the repeat count in the RC counter.
4. Execute the repeated program (loop).
The following instructions are used for executing 1 and 2:
The SETRC instruction is used to execute 3 and 4. Immediate data or a general register may be
used to specify the repeat count as the operand of the SETRC instruction:
#imm is 8 bits and the RC counter is 12 bits, so to set the RC counter to a value of 256 or greater,
use the Rm register. A sample program is shown below.
