#
|

# NOTES REGARDING DOWNLINK LISTS ASSOCIATED WITH THIS PROGRAM:
|
||||
# 1. DOWNLISTS. DOWNLISTS MUST BE COMPILED IN THE SAME BANK AS THE
|
||||
# DOWN-TELEMETRY PROGRAM. THIS IS DONE FOR EASE OF CODING, FASTER
|
||||
# EXECUTION.
|
||||
# 2. EACH DOWNLINK LIST CONSISTS OF A CONTROL LIST AND A NUMBER OF
|
||||
# SUBLISTS.
|
||||
# 3. A SUBLIST REFERS TO A SNAPSHOT OR DATA COMMON TO THE SAME OR OTHER
|
||||
# DOWNLINK LISTS. ANY SUBLIST CONTAINING COMMON DATA NEEDS TO BE
|
||||
# CODED ONLY ONCE FOR THE APPLICABLE DOWNLINK LISTS.
|
||||
# 4. SNAPSHOT SUBLISTS REFER SPECIFICALLY TO HOMOGENEOUS DATA WHICH MUST BE
|
||||
# SAVED IN A BUFFER DURING ONE DOWNRUPT.
|
||||
# 5. THE 1DNADR FOR THE 1ST WORD OF SNAPSHOT DATA IS FOUND AT THE END
|
||||
# OF EACH SNAPSHOT SUBLIST, SINCE THE PROGRAM CODING SENDS THIS DP WORD
|
||||
# IMMEDIATELY AFTER STORING THE OTHERS IN THE SNAPSHOT BUFFER.

# A. 1DNADR 1-WORD DOWNLIST ADDRESS.

# FILLED IN WITH 0001-0101. USED TO POINT TO A LIST OF N DOUBLE-

# C. DNCHAN DOWNLIST CHANNEL ADDRESS.

# SAME AS 1DNADR, BUT WITH PREFIX BITS 0111. USED TO POINT TO
|
||||
# A PAIR OF CHANNELS FOR DOWN TELEMETRY.

|
||||
# SAME AS CAF BUT TAGGED AS A CONSTANT. USED IN CONTROL LIST TO POINT TO A SUBLIST.
|
||||
# CAUTION --- A DNPTR CANNOT BE USED IN A SUBLIST.
