4.2.1
The Modulo Addressing scheme requires that a
starting 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

well as a W register field to specify the W address
registers. The XWM and YWM fields select which
