What do you mean by bitbang write only registers ? We are only writing to PORT and not reading them.

I am new to IAR Compiler and LPC MCUs but if somebody help me with an LED example then I will try to master LPC MCU programming in another 3 months.

I tried this but it didn't work. That's why I am asking. http://embeddedcraft.org/iar_arm2.html
 

When I sad write only I mean that you can only write to this register.
IO0SET |= value equal IO0SET = IO0SET | value - read, modify, write
The correct way is to write directly:
IO0SET = value

Man, you creating few topics per day with the same questions. Last time you crashed one PIC16F877 as I remember. Possible, beter way is to create one common topic like a "teaching Milan how to work with micronontrollers"
Iar, MikroC, PIC, LPC - doesn't matter.
