4.5.3
Like other DSPs, the SH-DSP has a modulo addressing mode. Address registers are updated in the
same way in this mode. When a modulo end address in which the address pointer value is already
set is reached, the address pointer becomes the modulo start address.
Modulo addressing is only effective for X and Y data transfer instructions (MOVX.W and
MOVY.W). When the DMX bit of the SR register is set, the X address register enters modulo
addressing mode; when the DMY bit is set, the Y address register enters modulo addressing mode.
Modulo addressing cannot be used on both X and Y address registers at once. Accordingly, do not
set DMX and DMY at the same time. Should they both be set at once, only DMY will be valid.
The MOD register is provided for specifying the start and end addresses for the modulo address
area. The MOD register stores the MS (modulo start) and ME (modulo end). The following shows
how to use the modulo register (MS and ME).
Note: There are four addressing methods (no update, index register addition (Is),
Modulo Addressing
increment, and decrement). Index register addition and increment are
post-increment methods. Decrement is a pre-decrement method.
+2/+4 (INC)
+0 (No update)
–2/–4 (DEC)
