SR also has a 12-bit repeat counter, RC, which is used for efficient loop control. The repeat start
register (RS) and repeat end register (RE) are also provided for loop control. They hold the start
and end addresses of a loop (the contents of the RS and RE registers are slightly different from the
actual loop start and end addresses). The modulo register, MOD, is provided to implement modulo
addressing for circular data buffering. MOD holds the modulo start address (MS) and modulo end
address (ME).
In order to access RS, RE, and MOD, load/store (control register) instructions for these registers
are provided. An example for RS is as follows:
Address set instructions for RS and RE are also provided.
