The LPC3141/3143 contains a rich set of specialized hardware interfaces, but the TFBGA
package does not contain enough pins to allow the use of all signals of all interfaces
simultaneously. Therefore a pin-multiplexing scheme is created, which allows the
selection of the right interface for the application.
Pin multiplexing is enabled between the following interfaces:
The pin interface multiplexing is subdivided into five categories: storage, video, audio,
NAND flash, and UART related pin multiplexing. Each category supports several modes,
which can be selected by programming the corresponding registers in the SysCReg.

Fast mode (400 kHz SCLwith 24 MHz APB clock; 325 kHz with12 MHz APB clock;
175 kHz with 6 MHz APB clock).
Interrupt support.
Supports DMA transfers (single).
Four modes of operation:
– Master transmitter
– Master receiver
– Slave transmitter
– Slave receiver
between the dedicated LCD interface and the external bus interface
between the NAND flash controller and the memory card interface
between UART and SPI
between I2STX_0 output and the PCM interface
