Claim 0:
1. A microcontroller system comprising:
a master microcontroller unit;
a plurality of slave microcontroller units; and
a plurality of general purpose inputs/outputs, wherein each of the plurality of general purpose inputs/outputs is operable in a first state and in a second state, wherein:
in the first state, the general purpose input/output is controlled by the master microcontroller unit; and
in the second state the general purpose input/output is controlled by one or more slave microcontroller units of the plurality of slave microcontroller units;

wherein the master microcontroller unit is arranged to transmit a selection signal which changes the state of a first general purpose input/output of the plurality of general purpose inputs/outputs; and
wherein a subset of the plurality of general purpose inputs/outputs are excluded from control by a subset of the plurality of slave microcontroller units.
