LPC435x/3x/2x/1x
32-bit ARM Cortex-M4/M0 microcontroller

[3] Pin VPP should either be not connected (when OTP does not need to be programmed) or tied to pins VDDIO and VDDREG to ensure
the same ramp-up time for both supply voltages.

level.
[15] The input cell disables the weak pull-up resistor when the applied input voltage exceeds V
