6. Configuration
6.1 Modifying the RSK+
This section lists the option links that are used to modify the way RSK+ operates in order to access different
configurations. Configurations are made by modifying link resistors or headers with movable jumpers or by
configuration DIP switches
A link resistor is a 0Ω surface mount resistor, which is used to connect or isolate parts of a circuit. Option links
are listed in the following sections, detailing their function when fitted or removed.
Bold, blue text indicates
the default configuration that the RSK+ is supplied with. Refer to the component placement diagram (§3) to
locate the option links, jumpers and DIP switches.
When removing soldered components, always ensure that the RSK+ 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 RX71M Group User’s Manual: Hardware and RSK+RX71M schematics for further information.
