Data Sheet

V2.0, 2001-05
Parallel Ports
The C164CI provides up to 59 I/O lines which are organized into five input/output ports
and one input port. All port lines are bit-addressable, and all input/output lines are
individually (bit-wise) programmable as inputs or outputs 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 three 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 3, Port 4, and Port 8 is selectable (TTL or CMOS like), where
the special CMOS like input threshold reduces noise sensitivity due to the input
hysteresis. The input threshold may be selected individually for each byte of the
respective ports.
All port lines have programmable alternate input or output functions associated with
them. All port lines that are not used for these alternate functions may be used as general
purpose IO lines.
PORT0 and PORT1 may be used as address and data lines when accessing external
memory, while Port 4 outputs the additional segment address bits A21/19/17 … A16 and
the optional chip select signals in systems where segmentation is enabled to access
more than 64 KBytes of memory.
Ports P1L, P1H, and P8 are associated with the capture inputs or compare outputs of
the CAPCOM units and/or serve as external interrupt inputs.
Port 3 includes alternate functions of timers, serial interfaces, the optional bus control
signal BHE/WRH, and the system clock output CLKOUT (or the programmable
frequency output FOUT).
Port 5 is used for the analog input channels to the A/D converter or timer control signals.
The edge characteristics (transition time) and driver characteristics (output current) of
the C164CI’s port drivers can be selected via the Port Output Control registers
(POCONx).
