Lpc2000

hi,


I would like to interface rtl8019 to bank3 of the lpc2292.

I tested my data and address bus, and I've got a interesting problem.
If I configure the bus to be 32bit, data and address is working properly.
PCB_PINSEL2 = 0x0F814924;
BCFG3 = 0x2000FFEF;

But if I configure it to be a 8 or even a 16bit bus, no data "come out".
BCFG3 = 0x1000FFEF; or BCFG3 = 0x0000FFEF;

I played with RBLE bit (0 or 1), but that not helped.

Any idea?
Thanks 
Andrew
