The Rising control register bits correspond to the input data bits. All IO can be set-up for
COS activity even if defined as an output. In most cases the output bits will be set to '0'
for the Rising register. When set '1' and the corresponding input bit transitions from low
to high the COS register of rising activity will be have the corresponding bit set. If the
separate interrupt enable bit is also set then an interrupt can be generated.
register is a control register. The COS data is read back separately.
