Each of the functional input/output blocks has a requirement for a defined number of the plurality of input/output pins wherein the total of the defined number for all of the plurality of functional input/output blocks exceeds the number of the plurality of input/output pins and wherein the processor core is interfaced with one of the input or output of each of the functional blocks. A reconfigurable interface selectively interfaces between the other of the input or output of the functional blocks and a select one or ones of the plurality of input/output pins, such that the processor core can be interfaced with the select one or ones of the input/output pins. The reconfigurable interface is operable to define how each of the plurality of input/output pins interfaces with the select ones of the plurality of functional blocks and the associated functionality in accordance with configuration information. A non-volatile memory is provided for storing information for use in association with the configuration information, such that the stored information can be altered.

Each of the plurality of transistors includes an n-well. An n-well generator connects a first voltage to the n-wells of the plurality of transistors of the output buffer in a first mode of operation when a system rail voltage exceeds a pad voltage applied to the output pad. The n-well generator connects the pad voltage to the n-wells of the plurality of transistors of the output buffer in a second mode of operation when the pad voltage applied to the output buffer exceeds the system rail voltage. A switching circuit is responsive to at least one control signal to connect the system rail voltage as the first voltage when the output pad is not driving an LCD display and to connect a larger of the system rail voltage and an LCD drive voltage as the first voltage when the output pad is driving the LCD display.
