Program memory
ROM
The program memory stores the program in-
structions that are to-be-executed. It also in-
cludes data, table and interrupt entries,
addressed by the program counter along with
the table pointer. The program memory size for
VDS84 is 2048 14. Certain locations in the pro-
gram memory are reserved for special usage:
Location 000H
This area is reserved for program initializa-
tion. The program always begins execution at
location 000H each time the system is reset.
Location 004H
This area is reserved for a Timebase interrupt
service program. If the Timebase counter
overflows, the interrupt is enabled and the
stackisnotfull,theprogrambeginsexecution
at location 004H.
Location 008H
This area is reserved for voice sampling rate
counter 1 interrupt service program. If the
timer interrupt results from a sampling rate
counter overflow, the interrupt is enabled and
the stack is not full, the program begins exe-
cution at location 008H.
Location 00CH
This area is reserved for voice sampling rate
counter 2 interrupt service program. If the
timer interrupt results from a sampling rate
counter overflow, the interrupt is enabled and
the stack is not full, the program begins exe-
cution at location 00CH.
