Functional Description CP384
2.8 CapROM EEPROM
The CapROM is a 4 kbit (512 byte) EEPROM which provides the capability to store board con-
trol relevant information to allow software configuration of the CP384.
2.9 Monitor and Control (M/C)
Various monitor and control functions are available for the operation of the CP384. The front
panel of the board is equipped with two LEDs for user-defined purposes. One green (RUN) and
one red (FAIL) have been placed on the front panel in anticipation of their most likely use. How-
ever they are freely programmable, the indicators being selected by the System Master (access
to the hardware debug register (hdr)).
The following table describes the digital input function modes of the CP384.
The system failure indicators regarding undervoltage and overvoltage are made available to
the DIO ProComm Controller, and are automatically reset by the voltage supervisor circuit once
the condition has been corrected.
An input signal (Reset) is available to set an inactive state for each individual output cluster and
also to shut down each individual output cluster during operation as necessary.
2.10 Software
Driver software is available for the System Master application software.

MODE DESCRIPTION
Event hit The CP384 monitors the input ports and detects any change in their state:
- Whenever individual input channels are enabled they are monitored.
- The direction of the change-of-state may be set.
- A status register reports the detected events.
Latch hit In addition to standard event detection (i.e. event-hit) there is a latch mode exten-
sion. This mode is used in the event that it is necessary to capture the inputs when
a defined event has occurred.
Compare hit It is possible to detect a complete input pattern automatically. The input vector is
continuously compared with the content of the mask register. Single inputs may also
be individually masked out.
