LPC5536 Flexcomm Voltage Rails

Hi,

on the LPC5536 64 Pin Package. I want to use 3.3V on VDDIO_1 and 1.8V on VDDIO_2 but it seems like there is no Flexcomm Peripheral that has all 4 SPI Signals within a single Voltage Domain.

They are always split up between VDDIO_1 and VDDIO_2 ... am i missing something or is this intentional ??

Unfortunately, this is chip design. I apologize for the inconvenience this may cause you. 

Best regards,
Omar
