RE: nRF5340 QSPI IFTIMING->RXDELAY setting

Simon,

I am asking if it's possible to set the QSPI clock to 24Mhz when RXDELAY is set to 6 and the 192MHz prescaler is set to 1.

Hi Kurt

The RXDELAY is the timing related to sampling of the input serial data. The value of RXDELAY specifies the number of prescaled 192MHz cycles delay from the rising edge of the SCK until the input data is sampled. RXDELAY set to 6 is the reset value which is the most most versatile RXDELAY that suits every frequency except the highest one.

Best regards,

Simon
