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.
Solved! Go to Solution.
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,
Jun Zhang
