2.7 Switch Information

The LMX1214 EVM can be operated in either pin mode or SPI mode. Pin mode allows basic configuration of the LMX1214 device without the need of a microcontroller. SPI mode provides full access to the LMX1214 device. Mode of operation is set via on-board switches SW2 to SW7. Headers are used to select power supply source.
