LPC1317 peripheral on almost any pins

[MJ1]

Hi

Is possible to reconnect/repin peripherals on LPC1317 HVQFN33 package to pins which are not intended in manual for that peripheral? I.e. UART/USART RXD, TDX signals to SPI MOSI, MISO - PIO0_21, PIO0_22 pins?

Thanks

No.

Just like with the power supply and clock oscillator pins, the peripheral switch matrix options per pin are defined by the silicon. The possible configuration options per pin are given in the datasheet.

Alternatively, you could use a larger package, or implement some functionality by "bit-banging" (like a "software UART").

Thanks so much.
