VIC068A-GC

VIC068A VMEbus Interface Controller Features Complete VMEbus interface controller and arbiter — 58 internal registers provide configuration control and status of VMEbus and local operations — Drives arbitration, interrupt, address modifier utility, strobe, address lines A07 through A01 and data lines D07 through D00 directly, and provides signals for control logic to drive remaining address and data lines — Direct connection to 68xxx family and mappable to non-68xxx processors Complete master/slave capability — Supports read, write, write posting, and block transfers — Accommodates VMEbus timing requirements with internal digital delay line (1⁄ 2-clock granularity) — Programmable metastability delay — Programmable data acquisition delays — Provides timeout timers for local bus and VMEbus transactions Interleaved block transfers over VMEbus — Acts as DMA master on local bus — Programmable burst count, transfer length, and interleaved period interval — Supports local module-based DMA Arbitration support — Supports single-level, priority and round robin arbitration — Supports fair request option as requester Interrupt support — Complete support for the VMEbus interrupts: interrupter and interrupt handler — Seven local interrupt lines — 8-level interrupt priority encode — Total of 29 interrupts mapped through the VIC068A Miscellaneous features — Refresh option for local DRAM — Four broadcast location monitors — Four module-specific location monitors — Eight interproc...
