The Starter Kit provides five push buttons. One is reserved for the reset circuit,
the other four can be connected to the V850E2/Px4 by jumpers.
All free push buttons can be used as I/O input or they can be used with the
multiplexed alternative function. Table 4-3 shows the interconnection between
the buttons and the microcontroller and one of the possible alternative functions.
