not applicable to the Deep power-down mode. Repeater mode may typically be used to
prevent a pin from floating (and potentially using significant power if it floats to an
indeterminate state) if it is temporarily not driven.
The input buffer for digital functions can be configured with hysteresis or as plain buffer
through the IOCON registers (see the LPC1100XL data sheet for details).

to use the pin in input mode.
In A/D-mode, the digital receiver is disconnected to obtain an accurate input voltage for
analog-to-digital conversions. This mode can be selected in those IOCON registers that
control pins with an analog function. If A/D mode is selected, Hysteresis and Pin mode
settings have no effect.
For pins without analog functions, the A/D-mode setting has no effect.

When output is selected, either by selecting a special function in the FUNC field, or by
selecting GPIO function for a pin having a 1 in its GPIODIR register, a 1 in the OD bit
