-          Several drivers have been copied from the related LPC17xx port but require integration into the LPC43xx:  ADC, DAC, GPDMA, I2C, SPI, and SSP.
-          The registers for these blocks are the same in both the LPC43xx and the LPC17xx and they should integrate into the LPC43xx very easily by simply adapting the clocking and pin configuration logic.

-          Other LPC17xx drivers were not brought into the LPC43xx port because these peripherals have been completely redesigned:  CAN, Ethernet, USB device, and USB host.
