LPC55S06 8 UART + 1 HS SPI

stefanardo — Tue, 11 Apr 2023 09:22:46 GMT

Hi,

I am trying to configure the LPC55S05JBD64 with 8 UART + 1 HS SPI but it seems it is impossible due to pin mux limitation? Is it true or I am making a mistake?

If I try to configure FLEXCOMM 2 as UART it seems RXD can be routed only on P0_26 the same as HS_SPI_MOSI.

Do you have any suggestion?

Regards.

Stefano

Thanks anyway Pavel, but I suggest to correct the information on the datasheet "UART up to 8, I2C up to 8, I2S up to 8 and SPI up to 6) + 1 HS SPI" for my knowledge of english language means that the HS SPI is excluded from the count of usable flexcomm.

Regards.
