@item -b @var{byte}
@itemx --byte=@var{byte}
-Keep only every @var{byte}th byte of the input file (header data is not
-affected). @var{byte} can be in the range from 0 to @var{interleave}-1,
-where @var{interleave} is given by the @option{-i} or @option{--interleave}
-option, or the default of 4. This option is useful for creating files
-to program @sc{rom}. It is typically used with an @code{srec} output
-target.
-
-@item -i @var{interleave}
-@itemx --interleave=@var{interleave}
-Only copy one out of every @var{interleave} bytes. Select which byte to
-copy with the @option{-b} or @option{--byte} option. The default is 4.
-@command{objcopy} ignores this option if you do not specify either @option{-b} or
-@option{--byte}.
+If interleaving has been enabled via the @option{--interleave} option
+then start the range of bytes to keep at the @var{byte}th byte.
+@var{byte} can be in the range from 0 to @var{breadth}-1, where
+@var{breadth} is the value given by the @option{--interleave} option.
+
+@item -i [@var{breadth}]
+@itemx --interleave[=@var{breadth}]
+Only copy a range out of every @var{breadth} bytes. (Header data is
+not affected). Select which byte in the range begins the copy with
+the @option{--byte} option. Select the width of the range with the
+@option{--interleave-width} option.
+
+This option is useful for creating files to program @sc{rom}. It is
+typically used with an @code{srec} output target. Note that
+@command{objcopy} will complain if you do not specify the
+@option{--byte} option as well.
+
+The default interleave breadth is 4, so with @option{--byte} set to 0,
+@command{objcopy} would copy the first byte out of every four bytes
+from the input to the output.
+
+@item --interleave-width=@var{width}
+When used with the @option{--interleave} option, copy @var{width}
+bytes at a time. The start of the range of bytes to be copied is set
+by the @option{--byte} option, and the extent of the range is set with
+the @option{--interleave} option.
+
+The default value for this option is 1. The value of @var{width} plus
+the @var{byte} value set by the @option{--byte} option must not exceed
+the interleave breadth set by the @option{--interleave} option.
+
+This option can be used to create images for two 16-bit flashes interleaved
+in a 32-bit bus by passing @option{-b 0 -i 4 --interleave-width=2}
+and @option{-b 2 -i 4 --interleave-width=2} to two @command{objcopy}
+commands. If the input was '12345678' then the outputs would be
+'1256' and '3478' respectively.
