6 Mbps on SPI.

[Eric Provost]

Hello. I'm working with the nrf52 with s132 loaded. There is a way to have a 6Mbps on the SPI ? I try the value 0x60000000 but this do not work. Thanks. Eric Provost.

Hi,

Anything over 4 MHz will be greatly influenced by pad and trace capacitance, so I would highly recommend checking the rise and fall time of your signal. You can generate a 5.3 MHz (16M / 3) signal by setting FREQUENCY = 0x48000000;, but not a 6 MHz frequency.

Cheers, Håkon

QSPI is only for the nRF52840, sorry for the mistake! Thanks for the comments, I'll relay your comments to the correct personnel internally. We're always open for feedback on our devices!
