No Operation. This service request performs no action other than to facilitate a Service Request
Acknowledge Interrupt (SACK). This would be used as a “UNIX ping-like” operation to detect the
presence of a channel group processor.
Soft Chip Reset. This is identical to a hardware reset. Set PORTMAP = 0, disable all supported ports
(both directions), and deactivate all 32 channels of all supported groups (both directions). The
Interrupt Status Descriptor is reset to point to the first dword in the queue, and all indicator bits are
reset.
Soft Group Reset. This is similar to a hardware reset for a specified group and direction. Disable all
specified ports (both directions), and deactivate all 32 channels of specified group (both directions).
Reserved.
Global Initialization. For the entire device, read the Global Configuration Descriptor and the Interrupt
Queue Descriptor from shared memory. This initialization is performed following a hardware or soft-
chip reset. The Interrupt Status Descriptor is reset to point to the first dword in the queue, and all
indicator bits are reset.
Group Initialization. For this group and direction, read the following from shared memory:
This initialization must be performed by the host driver for each group and each direction
immediately following any reset or global initialization.
