Watchdog Timer
The Watchdog Timer represents one of the fail-safe mechanisms which have been
implemented to prevent the controller from malfunctioning for longer periods of time.
The Watchdog Timer is always enabled after a reset of the chip, and can only be
disabled in the time interval until the EINIT (end of initialization) instruction has been
executed. Thus, the chip’s start-up procedure is always monitored. The software has to
be designed to service the Watchdog Timer before it overflows. If, due to hardware or
software related failures, the software fails to do so, the Watchdog Timer overflows and
generates an internal hardware reset and pulls the RSTOUT pin low in order to allow
external hardware components to be reset.
The Watchdog Timer is a 16-bit timer, clocked with the system clock divided by 2/128.
The high byte of the Watchdog Timer register can be set to a prespecified reload value
(stored in WDTREL) in order to allow further variation of the monitored time interval.
Each time it is serviced by the application software, the high byte of the Watchdog Timer
is reloaded. Thus, time intervals between 20
s and 336 ms can be monitored
(@ 25 MHz).
The default Watchdog Timer interval after reset is 5.24 ms (@ 25 MHz).
Parallel Ports
The C165 provides up to 77 I/O lines which are organized into six 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.
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 A23/19/17 … A16 in
systems where segmentation is enabled to access more than 64 KBytes of memory.
Port 6 provides optional chip select signals.
Port 3 includes alternate functions of timers, serial interfaces, the optional bus control
signal BHE/WRH, and the system clock output CLKOUT.
Port 5 is used for timer control signals.
