The SH-SDP additionally has a repeat start (RS) register, a repeat end (RE) register, and a modulo
(MOD) register.
The RS and RE registers are used to control program repetition (loops). The number of iterations
is specified in the SR register’s repeat counter (RC), the repeat start address is specified in the RS
register, and the repeat end address is specified in the RE register. The address values stored in the
RS and RE registers are not always the same as the physical starting address and ending address of
the repeat.
The MOD register uses modulo addressing to buffer the repeat data. Modulo addressing is
specified by DMX or DMY, the modulo end address (ME) is specified in the top 16 bits of the
MOD register, and the modulo start address (MS) is specified in the bottom 16 bits. The DMX and
DMY bits cannot simultaneously specify modulo addressing. Modulo addressing can be used for
X and Y data transfers (MOVX and MOVY). It cannot be used in single data transfers (MOVS).
Figure 2.4 shows the control registers. Table 2.1 shows the bits of the SR register.
