IP-CIO-32
P Counter/Timer & Parallel I/O
- The IP-CIP-32 uses two Zilog Z8536 counter/timer and parallel I/O devices.
- 16 bits of bidirectional, double buffered I/O from each CIO for a total of 32 bits can be bit programmable as input or output.
- Six, 16-bit counter/timers total are available.
- Timer port #1 and #2 take over 2 lines of the 8-bit port B.
- Two special 4-bit ports for handshake support for port A and B and timer port #3 output.
- All three timers can be linked together.
- Multiple interrupt sources including pattern matching on ports A and B.
- Total of 8 interrupt lines available.
- 8 or 32 MHz clock.
- 2 interrupts and 2 slave DMA IP bus lines.
- VITA 4 compliant.
- 2kbytes of EEPROM are used for board ID and user data storage.

Block Diagram and Operational Overview The IP-CIO-32 IP board has two Z8536 CIO’s from Zilog. The CIO consists of a CPU interface, three I/0 ports – A, B, and C – that consist of two general purpose 8-bit ports and one special purpose 4-bit port, three 16-bit counter/timers, an interrupt control logic block, and an internal control logic block. Both ports A and B include pattern recognition logic which allows interrupt generation when a specific pattern is detected. The pattern recognition logic can be programmed to make the port function like a priority interrupt controller. These same two ports can be concantenated to form a 16-bit word with handshake. The function of the special-purpose 4-bit port C depends upon the roles of ports A and B. Port C provides handshake lines when required by the other two ports. Port C also supports synchronization with DMA’s or CPUs. Port C has up to four port pins that can be used as dedicated external access lines for each counter/timer. Three different counter/timer output duty cycles are available – pulse, one-shot, and square-wave. The counter/timers can be programmed as either retriggerable or non-retriggerable. A 2kbyte EEPROM is used for the board ID and user data.
