STM32L476RG SPI gap between transmission

Hello all,

 

I'm trying to setup the STM32L476RG via SPI with an external DAC (SPI clock speed: 40MHz). I used the HAL_SPI_Transmit() function to transmit a 24Bit word.After one transmission there is a gap of 2.5µs befour the new transmission starts. For my application I need a fast transmission. Is there a posibility to purge the gap?

Thank you in advance,

Fabian
