 /******************************************************************************
- * Name:  rit_seldata
+ * Name:  lm3s_spicmddata
  *
  * Description:
  *   Set or clear the SD1329 D/Cn bit to select data (true) or command
  *   (false).  This function must be provided by platform-specific logic.
+ *   This is an implementation of the cmddata method of the SPI
+ *   interface defined by struct spi_ops_s (see include/nuttx/spi.h).
  *
  * Input Parameters:
  *
- *   devno - A value in the range of 0 throuh CONFIG_P14201_NINTERFACES-1.
- *           This allows support for multiple OLED devices.
- *   data - true: select data; false: select command
+ *   spi - SPI device that controls the bus the device that requires the CMD/
+ *         DATA selection.
+ *   devid - If there are multiple devices on the bus, this selects which one
+ *         to select cmd or data.  NOTE:  This design restricts, for example,
+ *         one one SPI display per SPI bus.
+ *   cmd - true: select command; false: select data
  *
  * Returned Value:
  *   None
