LPCXpresso845-MAX pin define

I did not find any documentation on the LPCXpresso845-MAX pin define on the official website, and I could not correspond to the pins on the board during the FW development process.

Hi,

As you know that the the LPC845 has SWM module(Switch Matrix Module), which enables the peripheral pin to route any port pin.

For example, if you write the code:

CLOCK_EnableClock(kCLOCK_Swm);

SWM0->PINASSIGN_DATA[0]=0x00;

SWM0->PINASSIGN_DATA[0]|=0x03|0x04<<8; //the P0_3 will function as uart_txd pin. the P0_4 will function as uart_rxd pin.

Hope it is helpful
