The shift is the number of bits. The value you enter is shifted left, from 0…15.
It is specified by the keyword ’Shift’, an equal sign, and the shift value.
The mask selects bits in the value you enter. It is specified by the
keyword’Mask’, an equal sign, and the mask value, usually in hexadecimal.
The value you enter is logically ANDed with the mask, shifted left by the shift
value, and ORed into the configuration word given by the offset.
Data Value
Data values can be defined as a numerical value or from a selection list.
Numerical values are defined in terms of a format (BcdSgn, BcdUns, BinSgn,
or BinSgn), the corresponding data value, mask and shift values, and minimum
and maximum values. Selection lists can contain up to 256 selection values.
The configuration dialog for a module created from the template displays the
names of the selection values.
EXAMPLE
Ofs=8 Mask=0x00ff Shift=2
