Modifying the Target Board for RX23W module

This section describes how to change the setting of this product by using option-link resistors.
An option-link resistor is a 0-Ω surface-mount resistor, which is used to short-circuit or isolate a part of circuits.
The subsequent sections contain lists of option-link resistors for individual functions. Fit or remove option-link
resistors to switch functions with reference to the list.
state of the configuration on the Target Board for RX23W as shipped. For the positions of the option links,
refer to chapter 3, Parts Layout.
When removing soldered components, do not apply a soldering iron to the Target Board for RX23W module for more
than 5 seconds. This time restriction is to avoid any damage components mounted nearby on the board.
