信息
MVME162串行端口1
Z85230的端口A接口为EIA-232-D DCE（数据电路终端
设备），并路由到标有串行端口的25针DB25连接器
1/MVME162前面板上的控制台。端口A也被路由到DB9/RJ11
（MVME712x上）或DB25（MVME712M上）连接器
MVME712系列转换模块。它在那里被标识为端口2。
虽然两个端口都连接到同一个Z85230端口A，但有
它们之间的一些差异：
❏ 在MVME162前面板上，端口1可连接到TxC和RxC
DB25连接器上可能存在的时钟信号。这些
通过MVME162板上的接头J11进行连接（见图
2章中的2-3和2-4）。TxC和RxC时钟在端口不可用
2在MVME712系列转换模块上。
❏ 在MVME712x转换模块上，端口2可以通过
DB9 DTE串行接口或（如果模块如此配备）通过
车载调制解调器及其标准RJ11（电信公司）插孔。这些联系是：
通过MVME712x上的跳线接头J16和J17进行。

VMEbus Interface and VMEchip2
The optional VMEchip2 provides the local-bus-to-VMEbus and VMEbus-tolocal-bus interfaces. The VMEchip2 can also provide the VMEbus system
controller functions. Refer to the MVME162 Embedded Controller Programmer’s
Reference Guide for detailed programming information. Refer to the MVME162
Embedded Controller Support Information manual for the pin assignments of
VMEbus backplane connectors P1 and P2.
Note that the ABORT switch logic in the VMEchip2 is not used. The GPI inputs
to the VMEchip2 which are located at $FFF40088 bits 7-0 are not used. The
ABORT switch interrupt is integrated into the MCchip ASIC at location
$FFF42043. The GPI inputs are integrated into the MCchip ASIC at location
$FFF4202C, bits 23-16.
I/O Interfaces
The MVME162 provides onboard I/O for many system applications. The I/O
functions include serial ports, IndustryPack (IP) interfaces, and optional
interfaces for LAN Ethernet transceivers and SCSI mass storage devices.
Serial Communications Interface
The MVME162 uses a Zilog Z85230 serial port controller to implement the two
serial communications interfaces. Each interface supports CTS, DCD, RTS,
and DTR control signals as well as the TxD and RxD transmit/receive data
signals, and TxC/RxC synchronous clock signals. The Z85230 supports
synchronous (SDLC/HDLC) and asynchronous protocols. The MVME162
hardware supports asynchronous serial baud rates of 110B/s to 38.4KB/s.
Functional Description

The Z85230 supplies an interrupt vector during interrupt acknowledge cycles.
The vector is modified within the Z85230 according to the interrupt source.
Interrupt request levels are programmed via the MCchip. Refer to the Z85230
data sheet listed in Chapter 1 and to the MCchip Programming Model in the
MVME162 Embedded Controller Programmer’s Reference Guide for further
information.
MVME162 Serial Port 1
Port A of the Z85230 is interfaced as EIA-232-D DCE (data circuit-terminating
equipment) and is routed to the 25-pin DB25 connector marked SERIAL PORT
1/CONSOLE on the MVME162 front panel. Port A is also routed to a DB9/RJ11
(on the MVME712x) or DB25 (on the MVME712M) connector on the
MVME712 series transition module. It is identified there as Port 2.
Although both ports are connected to the same Z85230 Port A, there are
several differences between them:
❏ On the MVME162 front panel, Port 1 can be connected to the TxC and RxC
clock signals which may be present on the DB25 connector. These
connections are made via header J11 on the MVME162 board (see Figures
2-3 and 2-4 in Chapter 2). The TxC and RxC clocks are not available at Port
2 on the MVME712 series transition modules.
❏ On MVME712x transition modules, Port 2 can be routed either through a
DB9 DTE serial interface or (if the module is so equipped1) through the
onboard modem and its standard RJ11 (Telco) jack. These connections are
made via jumper headers J16 and J17 on the MVME712x.
