PORT1 outputs the lower 16 bits of the last address if a demultiplexed bus mode is used,
otherwise the output pins of PORT1 represent the port latch data.
Port 4 outputs the segment address for the last access on those pins that were selected
during reset, otherwise the output pins of Port 4 represent the port latch data.
During Power Down mode the oscillator and the clocks to the CPU and to the
peripherals are turned off. Like in Idle mode, all port pins which are configured as general
purpose output pins output the last data value which was written to their port output
latches.
When the alternate output function of a port pin is used by a peripheral the state of this
pin is determined by the last action of the peripheral before the clocks were switched off.
The table below summarizes the state of all C161U output pins during Idle and Power
Down mode
