2.2.7 Interrupts
28236-DSH-001-B
The CN8236 informs the host of segmentation and reassembly activity by means
of maskable interrupts sent to the host processor, triggered by writes to the
segmentation and reassembly status queues.
interrupts at PDU boundaries (called Message Mode), or at data buffer
boundaries (called Streaming Mode).
can be enabled in order to reduce the interrupt processing load on the host. This
has value when the SAR resides in an environment in which the host is not
dedicated to data communications processing.
The user can configure the SAR to generate these status queue entries and
The CN8236 can also be configured with a status queue interrupt delay, which
