I used PIO1_3 on LPC1111 as SWDIO for debugging all the time, until I changed the pin function in my program by mistake. I changed it to GPIO. The problem is after I re-power the board, the SWDIO stil doesn't function. I can't use the SWIO for debugging anymore. But as its datasheet mentioned IOCON_SWDIO_PIO_3[FUNC] should be 0x0 after reset. Any way to fix it? Thanks.
