Normally, short-circuit B2 and B3.
When an External Regeneration Resistor is required, remove the short-circuit wire between B2 and B3,
and connect an External Regeneration Resistor between B1 and B2 as shown below.
Precautions for Correct Use
In
Regeneration
(4310 hex), set a value which is appropriate for the external regeneration
resistor that is connected. If you set a wrong value, the resistor may produce heat abnormally,
and fire or burning may result.
