This port is for designers to read control register from front-end.
-
For example, after setting the moving steps number (Reg 3D, 3E 3F) and
execute the moving command (Reg 0F), designers can get steps number which
has been moved via these registers. It can be reset to zero by CLRMCNT
command.
The unit is in quarter step.
-
Line number which scanner has finished.
For example, after setting the line number (Reg 25, 26 27) and execute the
scanning enable (bit 0 of Reg 01), designers can get line number which has been
finished via these registers. It can be reset to zero by CLRLNCNT command.
