ST10F168
12 - PARALLEL PORTS
The ST10F168 provides up to 111 I/O lines
organized into eight input / output ports and one
input port. All port lines are bit-addressable, and
all input / output lines are individually (bit-wise)
programmable as input or output via direction
registers. The I/O ports are true bidirectional ports
which are switched to high impedance state when
configured as inputs. The output drivers of five I/O
ports can be configured (pin by pin) for push-pull
operation or open-drain operation via control
registers. During the internal reset, all port pins
are configured as inputs.
The input threshold of Port 2, Port 3, Port 7 and
Port 8 is selectable (TTL or CMOS-like), where
the special CMOS-like input threshold reduces
noise sensitivity to the input hysteresis. The input
thresholds are selected with bit of PICON register
dedicated to blocks of 8 input pins (2-bit for Port2,
2-bit for Port3, 1-bit for Port7, 1-bit for Port8).
All pins of I/O ports also support an alternate pro-
grammable function:
32/74
– Port0 and Port1 may be used as address and
– Port 2, Port 7 and Port 8 are associated with the
– Port 3 includes the alternate functions of timers,
– Port 4 outputs the additional segment address
– Port 5 is used as analog input channels of the
– Port 6 provides optional bus arbitration signals
All port lines that are not used for alternate func-
tions may be used as general purpose I/O lines.
