PDS
(Periodic DPID Scheduler) A multi-dimensional array of pointers and data used by
the application’s periodic scheduler. The array contains the scheduled DPIDs,
DPID count down loop counters, and DPID data scheduling rate data.
N/A
PDS[].Transmit_Count
This variable is counter which decrements by 1 each time the
DecrementPDS_Counters() function is executed until the counter reaches $00.
Once the counter hits $00, the DPID shall be transmitted as soon as possible.
$00 to Slow_Rate_Count
PDS[].Scheduling_Rate
The scheduling rate for a scheduled DPID in the PDS.
Slow_Rate_Count,
Medium_Rate_Count, or
Fast_Rate_Count

PDS_Length
Reference to the maximum length of the PDS (maximum number of DPIDs that
can be scheduled simultaneously).
According to CTS
PDS_Number_Active
The number of active scheduled DPIDs in the PDS.
0 to PDS_length
PDS_Xmit_Index
This is an index variable which is used to keep track of the starting offset into the
PDS each time the Process_AA_Msgs() function is executed. This is necessary
to make sure that all DPIDs with expired timers will be sent before a single DPID
may be sent twice.
0 to (PDS_length -1)
AA_Msg_Rate
This is the amount of time between two executions of the Process_AA_Msgs()
function.
