LPC1833 - How set Drive strength of normal drive pins?

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.

Hello @ketulpatel

P6_5 is normal drive pin and we can't set it to high drive, the limit is on chip design.

According to UM, The pin configuration registers for high-drive pins control the following pins:
• P1_17
• P2_3 to P2_5

• P8_0 to P8_2
• PA_1 to PA_3

Hope this will help you,

Jun Zhang
