UART module

Explore M3 has 4-UARTs numbering 0-3, similarly the pins are also named as RXD0-RXD3 and TXD0-TXD3.As the LPC1768 pins are multiplexed for multiple functionalities, first they have to be configured as UART pins.
Below table shows the multiplexed UARTs pins.

Port Pin Pin Number PINSEL_FUNC_0 PINSEL_FUNC_1 PINSEL_FUNC_2 PINSEL_FUNC_3
P0.02 98 GPIO TXD0 ADC0[7]
P0.03 99 GPIO RXD0 ADC0[6]
P2_0 48 GPIO PWM1[1] TXD1
P0.1 49 GPIO PWM1[2] RXD1
P0.10 62 GPIO TXD2 SDA2 MAT3[0]
P0.11 63 GPIO RXD2 SCL2 MAT3[1]
P0.0 82 GPIO CAN1_Rx TXD3 SDA1
P0.1 85 GPIO CAN1_Tx RXD3 SCL1
