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 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 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 RX111 Group Hardware Manual and RSKRX111 schematics for further information.
