Field Documentation

unsigned mpc55xx_dspi_bus_entry::bus_number

Bus number (available after rtems_libi2c_register_bus()).

Note: You must set it in the initialization code after the bus registration.

mpc55xx_dspi_edma_entry mpc55xx_dspi_bus_entry::edma_push

eDMA entry for push data generation.

You can choose every available channel.

mpc55xx_dspi_edma_entry mpc55xx_dspi_bus_entry::edma_receive

eDMA entry for receiving.

The channel is fixed to a particular DSPI.

mpc55xx_dspi_edma_entry mpc55xx_dspi_bus_entry::edma_transmit
