The following memory allocation has been established as a standard programming
convention:
Decimal Location
0000 - 0007
0008 - 0031
0032 - 0511
512
- 1023
1024 - 7499
7500 - 7999
8000 - 8191
Contents
Program interrupt and controller
selector command words
Parameters for utility routines and
general use
Program constants, subroutine linkage
Scan words (channel tables) and constants
Object programs
Utility programs and programming tools
Loader programs
12.
The C-register instructions (PIC. AIC. XCZ. NCZ) will have decimal or symbolic
operands which will be assembled as a numerical value rather than a memory address.
13.
If
an operand referred to by a double length instruction (LDD, STD, BRS, AMD) falls
in an odd location, the operand will be stored in the next highest even location and a
"no-operation" instruction will be inserted in the vacated odd location.
BUFFER OPERATIONS
Bit Buffer Channel
Data is sent to a buffer via the transmit data drivers. Data is received from a buffer via the
receive data lines.
Control signals are sent to a buffer via EFD, the external function drivers.
Information as to the status of a buffer is tested via ESL, the external status lines.
