FLEXCOMM Pins of LPC55S69

[SrinathVelavan]

I am working on creating a custom device with LPC55S69 as Host MCU. For a peripheral that is interfaced with LPC55S69 on SPI interface, I have used Flexcomm 1 (Pins 13 & 14) as MOSI & MISO respectively and Flexcomm 3 ( Pin 7) for SSEL. Can we use 2 different Flexcomm interfaces (1 & 3) for the same peripheral or should all pins be in the same Flexcomm interface??

Hi,

Thank you so much for your interest in our products and for using our community.

All SPI signals must routed to the same Flexcomm instance.

Hope it helps you.

Have a nice day!
