12 Data Operation – FNC 40 to FNC 49
12.5 FNC 44 – BON / Check Specified Bit Status
2. 32-bit operation (DBON and DBONP)
The status (ON or OFF) of the bit "n" in [ +1, ] is output to .
[When the bit "n" is ON, is set to ON. When the bit "n" is OFF, is set to OFF.]
• When a constant (K) is specified as the transfer source [ +1, ], it is automatically converted into binary
format.
Caution
• Note that the 32-bit value [n+1, n] is valid when D or R is specified as "n" in a 32-bit instruction.
In the case of "DBON D0 M0 R0", "n" is [R1, R0].
Program example
When the bit 9 (n = 9) in D10 is "1" (ON), M0 is set to "1" (ON).
