Most of the input/output or control signals of the functional the C161U are realized as
alternate functions of pins of the parallel ports. There is, however, a number of signals
that use separate pins, including the USB interface, the oscillator, special control signals
and the power supply. Table 31 summarizes all dedicated pins of the C161U.
Table 31
Address Latch Enable signal ALE controls external address latches that provide a
stable address in multiplexed bus modes.
ALE is activated for every external bus cycle independent of the selected bus mode, ie.
it is also activated for bus cycles with a demultiplexed address bus. When an external
bus is enabled (one or more of the BUSACT bits set) also X-Peripheral accesses will
generate an active ALE signal.
ALE is not activated for internal accesses, ie. the internal RAM and the special function
registers. In single chip mode, ie. when no external bus is enabled (no BUSACT bit set),
ALE will also remain inactive for X-Peripheral accesses.
