LPC1833 Set Drive strength

Hello,

We are using LPC1833. We want to set Pin P6_5 with High-drive strength, but as per user manual this Pin P6_5 is not in the list of Pin configuration registers for high-drive pins.
How we can set it using software or need to set using it hardware?

Thanks,
Ketul

Hi,

For the LPC1833 microcontroller, the pins P6_5 to P6_8 are categorized as normal drive pins. This means they have a fixed, lower drive strength compared to high-drive pins, which are specifically designed to deliver higher current to drive heavier loads.

In general, normal-drive pins are not configurable for high drive strength, as they lack the necessary internal circuitry to support higher currents. So, for P6_5 to P6_8, the drive strength is limited to the default provided by the normal-drive configuration, and it cannot be increased through software or configuration settings.

Thanks,

Kushal
