RTC 4 RTC 5 unchanged primary functionality (offset definition), however:
• The parameters HeadNo and at_once are new.
• Extended offset value range.

The image field coordinates for the X and Y axes are specified as 20-bit values; in RTC
compatibility mode they are specified as 16-bit values (as with the RTC
multiplies the specified offset values by 16 (the permissible range of values is
correspondingly reduced to [–32768 ... 32767]).
