Individual interrupts are enabled by the two Interrupt Mask Registers. The host
processor may determine the cause of the interrupt by reading the two Interrupt
Status Registers, which provide the current state of interrupt events and
conditions. The Interrupt Status Registers may be updated in two ways. In one
interrupt handling mode, a particular bit in Interrupt Status Register #1 or #2 will
be updated only if the event occurs and the corresponding bit in Interrupt Mask
Register #1 or #2 is enabled.
In the enhanced interrupt handling mode, a
particular bit in the one of the Interrupt Status Registers will be updated if the
event/condition occurs regardless of the value of the corresponding Interrupt
Mask Register bit. In either case, the respective Interrupt Mask Register (#1 or
#2) bit is used to enable an interrupt for a particular event/condition.
The PCI Enhanced Mini-ACE supports all the interrupt events from ACE/Mini-
ACE (Plus) and Enhanced Mini-ACE including RAM Parity Error, Transmitter
Timeout, BC/RT Command Stack Rollover, MT Command Stack and Data Stack
Rollover, Handshake Error, BC Retry, RT Address Parity Error, Time Tag
Rollover, RT Circular Buffer Rollover, BC Message, RT Subaddress, BC End-of-
Frame, Format Error, BC Status Set, RT Mode Code, MT Trigger, and End-of-
Message.
For the PCI Enhanced Mini-ACE’s Enhanced BC mode, there are four user-
defined interrupt bits. The BC Message Sequence Control Engine includes an
instruction enabling it to issue these interrupts at any time.
For RT and Monitor modes, the PCI Enhanced Mini-ACE architecture include an
Interrupt Status Queue. This provides a mechanism for logging messages that
result in interrupt requests. Entries to the Interrupt Status Queue may be filtered
such that only valid and/or invalid messages will result in entries on the queue.
The PCI Enhanced Mini-ACE incorporates additional interrupt conditions beyond
ACE/Mini-ACE (Plus), based on the addition of Interrupt Mask Register #2 and
Interrupt Status Register #2. This is accomplished by chaining the two Interrupt
Status Registers using the INTERRUPT CHAIN BIT (bit 0) in Interrupt Status
Register #2 to indicate that an interrupt has occurred in Interrupt Status Register
Additional interrupts include “Self-Test Completed”, masking bits for the
Enhanced BC Control Interrupts, 50% Rollover interrupts for RT Command
Stack, RT Circular Buffers, MT Command Stack, and MT Data Stack; BC Op
Code Parity Error, (RT) Illegal Command, (BC) General Purpose Queue or
(RT/MT) Interrupt Status Queue Rollover, Call Stack Pointer Register Error, BC
Trap Op Code, and four User-Defined interrupts for the Enhanced BC mode.
RAM PARITY
The BC/RT/MT version of the PCI Enhanced Mini-ACE is available with options of
4K or 64K words of internal RAM. For the 64K option, the RAM is 17 bits wide. The
64K X 17 internal RAM allows for parity generation for RAM write accesses, and
