Hello,
I have already read topic about GPIO 0_5, open collector problem but I found new problem.
I connected LED to this pin to VCC.
I set pin 0_5 as GPIO as out put and value for output as "1' (led off)
I set up Timer CT16B0 for irq.
When irq is handled pin 0_5 goes down, and led is on. <deleted>
I think is great idea to make new blinky.asm src without touching io_pins .. word first? ;)
For me is hugh mistake and I really don't know what I can do with this error.

LPC 1114 302, LPCXPRESSSO 5.0.19.
I use asm only in project to have best cycle exact application. I don't understand why irq state can change state of pinout.


PS. is this possible that .ltorg cause problems?
