Hello Forum Member,


To simplify I have left the remaining settings




const XMC_SPI_CH_CONFIG_t SPI_U2C1_config =
{
.baudrate = 72000000, // 72 MHz
};

XMC_SPI_CH_SetTransmitMode(XMC_SPI2_CH1, XMC_SPI_CH_MODE_QUAD); // Set QUAD MODE for SPI Channel
XMC_SPI_CH_Init(XMC_SPI2_CH1, &SPI_U2C1_config);




What is the maximum Baudrate for the USIC Peripheral when I used it as QSPI.

PERIPHERAL / 2, or in my case 144 MHz(as a maximum frequency) / 2 = 72 MHz.

Or I overlook something in the data sheet, which limits the maximum frequency..


Best regards
