VMIVME-6015 是一款四通道、多功能串行输入/输出 （SIO） 外设接口板，旨在满足 VMEbus 系统中的各种串行数据通信要求。VMIVME-6015 的基本功能是串口到并行、并口到串口的控制器;但是，它是软件可配置的，因此其“个性”可以针对任何给定的串行数据通信应用进行优化。

VMIVME-6015 能够处理异步协议、同步面向字节的协议（如 IBM Bisync）和同步面向位的协议（如 HDLC 和 IBM SDLC）。该SIO控制器还可用于支持除数据通信以外的应用（例如盒式磁带或软盘接口）的几乎任何串行协议。

VMIVME-6015 可以在任何同步模式下生成和检查字符识别码 （CRC），并且可以编程以在各种模式下检查数据完整性。该控制器还具有调制解调器控制功能，在不需要这些控制的应用中，调制解调器控制可用于通用 I/O。 VME-6015 设计有两个MK68564 SIO 双通道多功能外围电路，支持自检功能。

当在命令寄存器中设置环路模式位时，环路模式被激活以支持内置测试功能。

The VMIVME-6015 is a four-channel, multifunctional serial input/output (SIO) peripheral interface board designed to meet various serial data communication requirements in VMEbus systems. The basic function of VMIVME-6015 is the controller from serial port to parallel port and parallel port to serial port. However, it is software-configurable, so its "personality" can be optimized for any given serial data communication application.

The VMIVME-6015 is capable of handling asynchronous protocols, synchronous byte-oriented protocols such as IBM Bisync, and synchronous bit-oriented protocols such as HDLC and IBM SDLC. The SIO controller can also be used to support almost any serial protocol for applications other than data communication, such as cassette tape or floppy disk interfaces.

The VMIVME-6015 can generate and check character identification codes (CRC) in any synchronization mode, and can be programmed to check data integrity in a variety of modes. The controller also features modem controls, which can be used for general-purpose I/O in applications where these controls are not required. The VME-6015 is designed with two MK68564 SIO dual-channel multifunctional peripheral circuits that support self-testing.

When the loop mode bit is set in the command register, loop mode is activated to support the built-in test function.
