SPI GTL Receive Callback Function

Hi all,

In order to be able to debug some of the problems I'm having, I would like to know which function handles the reception of incoming SPI GTL messages in an external uC configuration. I used the proximity reporter example as a starting point. In spi_hci.c I can see that a callback function is called in spi_receive_data_isr(). This callback is set through the spi_hci_read_func() function. However, I am not able to trace back this callback (I end up in jump_table.c).

Could you please point me to the function that handles incoming GTL SPI messages?

Thanks,
mabraun

EDIT: I am talking about the DA1458x (slave) side here.
