Hi,

Kind of right... but Pinsel2 should be: &= 0xFFFFFFF3;

bits 0..1 are reserved with reset value 0x0 (obviously And them with 1 to
preserve)
bit 2 is 0 for GPIO for P1.16-31 and 1 to turn on Debug Port
bit 3 is 0 for GPIO for P1.16-31 and 1 to turn on Trace

table 63 in the manual for pinsel2.

Hmm it might be my advice is no good, as I was looking in the LPC2148
manual. Sorry.
