Mask

Use the -mask=spec option to logically AND a memory range with a particular bitmask. This is used to ensure that the unimplemented bits in program words (if any) are left blank. The usage of this option is as follows:

-mask=hexcode@start-end

where hexcode is a value that will be ANDed with data within the start to end address range. All values are assumed to be hexadecimal. Multibyte mask values can be entered in little endian byte order.
