4.2.1
The Modulo Addressing scheme requires that a start-
ing and an ending address be specified and loaded
into the 16-bit
XMODSRT, XMODEND, YMODSRT and YMODEND
(see
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).

The Modulo and Bit-Reversed Addressing Control reg-
ister 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 oper-
ate with Modulo Addressing. If XWM = 15, X RAGU
and X WAGU Modulo Addressing is 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
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>.
