Explanation of function and operation
1. 16-bit operation (BON and BONP)
The status (ON or OFF) of the bit "n" in 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 , it is automatically converted into binary format.
