Dedicated Pins Output Control
Programmable pad drivers also are supported for the dedicated pins ALE, RD and WR. For these pads, a
special POCON20 register is provided.

12.1.4 - Alternate Port Functions
Each port line has one associated programmable
alternate input or output function. PORT0 and
PORT1 may be used as the address and data
lines when accessing external memory.
Port 4 outputs the additional segment address bits
A23/A19/A18/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.
Port 2, Port 7 and Port 8 are associated with the
capture inputs or compare outputs of the CAPCOM
units and/or with the outputs of the PWM module.
Port 2 is also used for fast external interrupt inputs
and for timer 7 input.
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 5 is used for the analog input channels to the
A/D converter or timer control signals.

Function
If an alternate output function of a pin is to be
used, the direction of this pin must be pro-
grammed for output (DPx.y=‘1’), except for some
signals that are used directly after reset and are
configured automatically. Otherwise
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
(except for PWM output signals).
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 latch.
This can be used for testing purposes to allow a
software trigger of an alternate input function by
writing to the port output latch.
