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.
Table 6-1 below shows the RSK+RZ/A1H default configuration with respect to the peripheral functionality.
Bold, blue text
indicates the default configuration that the RSK is supplied with. It is noted that certain
peripheral functions are disabled by default, as shown in Table 6.1 in the column entitled
Secondary
Function
. It is possible to activate these disabled peripherals, but at the expense of the default peripheral
functions as shown in the Table. Refer to the sections cited in the Table in order to perform any required
modifications.
When removing soldered components, always ensure that the RSK is not exposed to a soldering iron for intervals
greater than
five
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 RZ/A1H Group Hardware Manual and RSK+RZA1H schematics for further information.

Table 6.1: RSK Default Configuration by Function
* The primary and secondary functions depend on the port pin these two functions share.
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. Refer to the component
placement diagram (Figure 3.3, Figure 3.4) to locate the option links and jumpers.
Bold, blue text

the default configuration that the RSK is supplied with.
