LPC5411x
32-bit ARM Cortex-M4/M0+ microcontroller
• Digital input: Repeater mode enabled/disabled.
• Z mode; High impedance (no cross-bar currents for floating inputs).
The default configuration for standard I/O pins is Z mode. The weak MOS devices provide
a drive capability equivalent to pull-up and pull-down resistors.
The glitch filter rejects pulses of typical 12 ns width.
