8.1.2. Function of Control Output
 You can set control output function, output logic and stability timer to the output ports. This
function permits you to change the preset input port function to other function, and to switch to
one of extended functions.
◊ You may set the same function to multiple output ports.
◊ When setting an output function that is not included in the shipping set, you can
interchange it with a preset function.
For example, you may integrate the DRDY and WRN outputs to the NRM output, or
integrate OTPA and OTPM outputs to increase the number of idle ports.
