The boundary condition also needs to be considered. The line length (pixels/line) of the bi-level resolution

conversion input and output data is a multiple of 16 (See the bi-level resolution conversion section for details). If

we insert different number of zeros in the beginning of lines, all the lines will end at different columns (not end at

the same halfword boundary). Therefore, control bits need to be used. It indicates the total number of halfwords of

zeros that needs to be added either at the beginning and at the end of each line (See the diagram below). 0 - 4

halfwords can be set in the register.

324 halfwords / line
