4.2.1
The Modulo Addressing scheme requires that a
starting and an end address be specified and loaded
into the 16-bit Modulo Buffer Address registers:
XMODSRT, XMODEND, YMODSRT and YMODEND
(see Table 3-3).
The length of a circular buffer is not directly specified. It
is
corresponding start and end addresses. The maximum
possible length of the circular buffer is 32K words
(64 Kbytes).

4.2.2
The Modulo and Bit-Reversed Addressing Control
register MODCON<15:0> contains enable flags, as
well as a W register field to specify the W address
registers. The XWM and YWM fields select which
registers will operate with Modulo Addressing. If
XWM = 15, X RAGU and X WAGU Modulo Addressing
are disabled. Similarly, if YWM = 15, Y AGU Modulo
Addressing is disabled.
The X Address Space Pointer W register (XWM), to
which Modulo Addressing is to be applied, is stored in
MODCON<3:0> (see Table 3-3). Modulo Addressing is
enabled for X data space when XWM is set to any value
other than 15 and the XMODEN bit is set at
MODCON<15>.
The Y Address Space Pointer W register (YWM), to
which Modulo Addressing is to be applied, is stored in
MODCON<7:4>. Modulo Addressing is enabled for Y
data space when YWM is set to any value other than 15
and the YMODEN bit is set at MODCON<14>.
