Normal Operation
Depending on the format type, different record fields are used for output and input. The variable x
stands for the written or read value.
- DOUBLE format (e.g.
%f
): - Not allowed.
- LONG format (e.g.
%i
): - If
MASK==0
(because NOBT
is not set): - Output:
x=VAL
Input: VAL=x
- If
MASK!=0
: - Output:
x=RVAL&MASK
Input: RVAL=x&MASK
MASK
is initialized to NOBT
1-bits shifted left by SHFT
.- ENUM format (e.g.
%{
): - Not allowed.
- STRING format (e.g.
%s
): - Not allowed.
In my case, I use mbbiDirect and get a value as 0x29 (b"0010,1001") in VAL field. If I want to mask it with a value 0xC1(b"1100,0001"), how to set NOBT/SHFT field?
Thanks a lot in advance.
