VMIVME-7750 VMEbus接口由圍繞Tundra Semiconductor Corporation Universe II VMEbus界面芯片構建的PCI到VMEbus橋接器提供。Universe II在一個(gè)設計中提供了可靠的高性能64位VMEbus到PCI接口?；赨niverse的VMEbus接口的功能和編程在標題為：VMIC的Tundra Universe II based VMEbus interface Product manual I 2C Support的配套手冊中詳細介紹。VMIVME-7750支持I2C總線(xiàn)，可以根據Philips Semiconductor開(kāi)發(fā)的I2C總線(xiàn)規范2.0版作為I2C總線(xiàn)主控器或從控器運行。通過(guò)使用National Semiconductor Super I/O I2C總線(xiàn)控制器實(shí)現I2C總線(xiàn)上的通信。該控制器能夠使用中斷或輪詢(xún)握手在I2 C總線(xiàn)上進(jìn)行字節通信，并在主模式下運行時(shí)支持可編程時(shí)鐘速率。
The VMIVME-7750 VMEbus interface is provided by the PCI-to-VMEbus bridge built
around the Tundra Semiconductor Corporation Universe II VMEbus interface chip.
The Universe II provides a reliable high-performance 64-bit VMEbus-to-PCI interface
in one design. The functions and programming of the Universe-based VMEbus
interface are addressed in detail in a companion manual titled: VMIC’s Tundra
Universe II Based VMEbus Interface Product Manual I
2C Support
The VMIVME-7750 supports the I2C-bus and can operate as an I2C-bus master or
slave per the I2
C-bus specification, version 2.0, developed by Philips Semiconductor.
Communication over the I2C-bus is accomplished through the use of the National
Semiconductor Super I/O I2C-bus controller. This controller is capable of
communicating on the I2
C-bus on a byte-wise basis using interrupt or polled
handshaking and supports a programmable clock rate when operating in Master
mode.
