3.3.5 Miscellaneous Request Structures
3.3.5.1
STATUS_REQ
Structure
Used to indicate the internal state of the
SEC2
core as well as the driver after the occurrence of an event. Returned
as a pointer by

and embedded in all requests. This structure is defined in
Sec2Notify.h
Each element is a copy of the contents of the same register in the
SEC2
driver. This structure is also known as
SEC2_STATUS
through a typedef.
unsigned long ChaAssignmentStatusRegister[2];
unsigned long InterruptControlRegister[2];
unsigned long InterruptStatusRegister[2];
unsigned long IdRegister;
unsigned long ChannelStatusRegister[NUM_CHANNELS][2];
unsigned long ChannelConfigurationRegister[NUM_CHANNELS][2];
unsigned long CHAInterruptStatusRegister[NUM_CHAS][2];
unsigned long QueueEntryDepth;
unsigned long FreeChannels;
unsigned long FreeAfhas;
unsigned long FreeDesas;
unsigned long FreeMdhas;
unsigned long FreePkhas;
unsigned long FreeAesas;
unsigned long FreeKeas;
unsigned long BlockSize;
3.3.5.2

structure contains the original request structure as well as an error and driver status.
