MA17503 MA17503 Radiation Hard MIL-STD-1750A Interrupt Unit Replaces June 1999 version, DS3566-4.0 DS3566-5.0 January 2000 The MA17503 Interrupt Unit is a component of the MAS281 chip set. Other chips in the set include MA17501 Execution Unit and the MA17502 Control Unit. Also available is the peripheral MA31751 Memory Management/Block Protection Unit. The lnterrupt Unit, in conjunction with these additional chips, implements the full MIL-STD-1750A Instruction Set Architecture. The MA17503 - consisting of the Pending Interrupt Register, Mask Register, Interrupt Priority Encoder, Fault Register, Timer A, Timer B, Trigger-Go Counter, Bus Fault Timer, and DMA interface - handles all interrupt fault, and DMA interfacing, in addition to providing all three hardware timers.
