I have running SPI-Master with DMA for TX und RX, transfer is started via function

XMC_USIC_CH_TriggerServiceRequest(XMC_SPI1_CH0, 0);

Is it possible to start the SPI with an external PIN ?
I want to trigger a transer with an external PIN without any software functions,

Hi,

Please have a look to the ERU_EXTINT example in the XMCLib distribution.
