6. Configuration

6.1 Modifying the RSK

This section lists the option links that are used to modify the way CPU board operates in order to access
different configurations. Configurations are made by modifying link resistors or headers with movable jumpers.
A link resistor is a 0Ω surface mount resistor, which is used to short or isolate parts of a circuit. Option links
are listed in the following sections, detailing their function when fitted or removed.
the default configuration that the CPU board is supplied with. Refer to the component placement diagram
(section 3) to locate the option links, jumpers.
When removing soldered components, always ensure that the CPU board is not exposed to a soldering iron for
intervals greater than 5 seconds. This is to avoid damage to nearby components mounted on the board.
When modifying a link resistor, always check the related option links to ensure there is no possible signal contention
or short circuits. Because many of the MCU's pins are multiplexed, some of the peripherals must be used exclusively.
Refer to the RX140 Group User's Manual: Hardware and CPU board schematics for further information.
In the table in this section, "pin" expression is omitted, so please read as follows.
Example: U6.3 -> U6.3pin
