Can we change default GPIO settings of LPC1768 through Hardware?

[anooprs]

Hi, I started using LPC1768 and LPC11U68 ICs recently. Before that I worked with different controller, in which the default condition of GPIOs where pulled down. I written program for that controller so that my peripherals will be initialized, as I needed, from switching ON the controller. Now I migrated to LPC devices. I, some how, imported my entire codes to LPC and it was getting programmed. But in LPC devices the default condition of every GPIOs are PULLED UP. Now I need to edit my codes and is not at all an easy job, since my codes contain thousands of lines now. So is there any way that I can play with hardware of LPC devices to make all GPIOs default conditions as I need?

Hi Anoop R S,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.

-- No, I'm afraid it's unavailable to make it, as either of LPC1768 or LPC11U68 doesn't support this feature.
Hope this is clear.

Have a great day,
