Alternate Port Functions
Each port line has one programmable alternate input or output function associated.
PORT0 and PORT1 may be used as the address and data lines when accessing
external memory.
Port 2 is used for fast external interrupt inputs.
Port 3 includes alternate input/output functions of timers, serial interfaces, the optional
bus control signal BHE/WRH and the system clock output (CLKOUT).
Port 4 outputs the additional segment address bits A20/A19/A17...A16 in systems where
more than 64 KBytes of memory are to be accessed directly.
Port 6 provides the optional chip select outputs and the bus arbitration lines.
If an alternate output function of a pin is to be used, the direction of this pin must be
programmed for output (DPx.y=‘1’), except for some signals that are used directly after
reset and are configured automatically. Otherwise the pin remains in the high-impedance
state and is not effected by the alternate output function. The respective port latch should
hold a ‘1’, because its output is ANDed with the alternate output data.
Note: DP0L and, if a 16 bit external XBus data bus is used, also DP0H must be ’0’ as
long as the XBUS is active.
If an alternate input function of a pin is used, the direction of the pin must be programmed
for input (DPx.y=‘0’) if an external device is driving the pin. The input direction is the
default after reset. If no external device is connected to the pin, however, one can also
set the direction for this pin to output. In this case, the pin reflects the state of the port
output latch. Thus, the alternate input function reads the value stored in the port output
