Lpc2000

Has anybody implemented NAND flash driver on LPC210x ?

Now we are considering using LPC2106 in our project which needs
a NAND flash to storage data.
Two UARTs, I2C and SPI are all used for other functions.
If p0.23 to p0.31 is used for NAND flash data pins, it will occupy 
the pins for JTAG2, so that we can't use JTAG to debug anymore.

Any idea on it ?
