Hello.
In the LPC82X data sheet, it is recommended to disable unused pins and output LOW in the output mode, but is it also possible to disable pull-down?
The MODE bit in the IOCON register is
0x0 Inactive (no pull-down / pull-up resistor enabled).
0x1 Pull-down resistor enabled.
0x2 Pull-up resistor enabled.
0x3 Repeater
So, which one is recommended, 0x0 or 0x01?
Sorry, I do not have much knowledge of hardware.

Hi Jun
Make the unused pin as floating, and then set it as output low in software. GPIO output with pull-up disabled, and pull-down enabled.
Have a great day,
