The value in this field specifies the number of 32 bit words,
minus 1, that are needed to contain all of the pixels that
comprise width of the display. The value of LEN is
determined by:
1) Find how many pixels occupy a 32-bit word. For
example, four 8-bit pixels can occupy a 32-bit word.
2) Find the width of the display in pixels. For example, a
640x480 display has a width of 640 pixels.
3) The line length, LEN, is determined by the stride of the
display, that is, how many 32-bit words are needed to
populate the width of the display with pixels. From steps 1
and 2, the stride for this example is 640 pixels divided by
4, where 4 is the number of 8-bit pixels that occupy a
word. So, for this example, LEN = 640 / 4 = 160 = 0xA0.
Usually the same LEN value is used in both the
SRCLINELENGTH
register.

For Block Fill and Block Copy functions, the value in this
field specifies the number of 32-bit words, minus 1, that
are needed to contain the pixels in the 1st scan line of the
destination image. For example, please refer to the note in
Section 8.5.2.4 on page
field is 0xFFE = 4095 words.
