3. Configure Hardware

The EVBMA6X02BMU has several configuration options. The most important ones are the clock and SPI configuration of the BMA6X02S.

3.1 Clock Configuration

The BMA6X02S has three clock configuration options. It can operate with an internal clock, an external crystal or an external clock source. The default configuration is the external clock source, where it is assumed that the S35K358 is configured to provide this clock to the pin OSCP. The OSCP pin is connected on the board to the pin PTB5_47_CLKOUT_RUN_TP8. A change of the clock source selection can be done with R429, R430, R431 and R432 (see Figure 2). Refer to the BMA6X02S data sheet for details on how to change the configuration.

Note: The BMA6X02S must have either a proper external clock signal, or an update of the configuration to use the internal oscillator instead.

3.2 SPI Configuration

The BMA6X02S has three SPI configurations. It can operate as a single or a dual SPI with the response SPI as a controller or a target. The default configuration of the EVBMA6X02BMU is the dual SPI configuration. The configuration can be changed with R439, R440 and R441 (see Figure 3). Ensure that the hardware configuration used is matching to the software configuration of the S32K358.
