Each interface supports the CTS, DCD, RTS, and DTR control signals as
well as the TxD and RxD transmit/receive data signals, and TxC/RxC
synchronous clock signals. Since not all modem control lines are available
in the Z85230, a Z8536 CIO is used to provide the missing modem lines.
A PAL device performs decoding of register accesses and pseudo interrupt
acknowledge cycles for the Z85230 and the Z8536 in ISA I/O space. The
PIB controller supplies DMA support for the Z85230.The Z85230 receives a 10 MHz clock input. The Z85230 supplies an
interrupt vector during pseudo interrupt acknowledge cycles. The vector is
modified within the Z85230 according to the interrupt source. Interrupt
request levels are programmed via the PIB controller. Refer to the Z85230
data sheet and to the MVME2600/2700 Series Single Board Computer
Programmer’s Reference Guide for further information.
Z8536 CIO Device
The Z8536 CIO device complements the Z85230 ESCC by supplying
modem control lines not provided by the Z85230 ESCC. In addition, the
Z8536 CIO device has three independent 16-bit counters/ timers. The
Z85230 receives a 5 MHz clock input.
Base Module Feature Register
The Base Module Feature Register contains the details of the MVME2700
single board computer’s configuration. It is an 8-bit read-only register
located on the base board at ISA I/O address $0802.SCCP? Z85230 ESCC present. If set, there is no on-board
synchronous serial support (the ESCC is not present). If
cleared, the Z85230 ESCC is installed and there is on-board
support for synchronous serial communication.
PMC2P? PMC/PMCIX slot 2 present. If set, no PCI mezzanine card (or
PCI expansion device) is installed in PMC slot 2. If cleared,
PMC/PMCIX slot 2 contains a PCI mezzanine card (or PCI
expansion device).
PMC1P? PMC slot 1 present. If set, no PCI mezzanine card is installed
in PMC slot 1. If cleared, PMC slot 1 contains a PCI
mezzanine card.VMEP? VMEbus present. If set, there is no VMEbus interface. If
cleared, the VMEbus interface is supported.
LANP? Ethernet present. If set, no Ethernet transceiver interface is
installed. If cleared, there is on-board Ethernet support.
SCSIP? SCSI present. If set, there is no on-board SCSI interface. If
cleared, on-board SCSI is supported.
