82596CA
Events can be cleared only by CPU acknowledgment If some events are not acknowledged by the ACK field
the Interrupt signal (INT) will be reissued after Channel Attention (CA) is processed Furthermore if a new
event occurs while an interrupt is set the interrupt is temporarily cleared to trigger edge-triggered interrupt
controllers
The CPU uses the Channel Attention line to cause the 82596 to examine the SCB This signal is trailing-edge
triggered the 82596 latches CA on the trailing edge The latch is cleared by the 82596 before the SCB
control command is read
