The lower byte of the program counter (PCL) is
a readable and writeable register (06H).
Moving data into the PCL performs a short
jump. The destination will be within 256 loca-
tions.
When a control transfer takes place, an addi-
tional dummy cycle is required.
Program memory
ROM
The program memory is used to store the pro-
gram instructions which are to be executed. It
also contains data, table, and interrupt entries,
and is organized into 4096 15 bits, addressed
by the program counter and table pointer.
Certain locations in the program memory are
reserved for special usage:
Location 000H
This area is reserved for program initializa-
tion. After chip reset, the program always be-
gins execution at location 000H.
Location 004H
This area is reserved for the external inter-
rupt service program. If the INT input pin is
activated, the interrupt is enabled and the
stackisnotfull,theprogrambeginsexecution
at location 004H.
Location 008H
This area is reserved for the timer/event coun-
ter0interruptserviceprogram.Ifatimerinter-
rupt results from a timer/event counter 0
overflow,andiftheinterruptisenabledandthe
stack is not full, the program begins execution
at location 008H .
