Preliminary
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-
ter interrupt service program. If a timer inter-
rupt results from a timer/event counter
overflow,andiftheinterruptisenabledandthe
stack is not full, the program begins execution
at location 008H.
Table location
Any location in the PROM space can be used
as look-up tables. The instructions "TABRDC
[m]" (the current page, 1 page=256 words)
and "TABRDL [m]" (the last page) transfer
the contents of the lower-order byte to the
specified data memory, and the higher-order
byte to TBLH (08H). Only the destination of
the lower-order byte in the table is
well-defined, the other bits of the table word
are transferred to the lower portion of TBLH,
and the remaining 2 bits are read as "0". The
Table Higher-order byte register (TBLH) is
read only. The table pointer (TBLP) is a
read/write register (07H), which indicates the
table location. Before accessing the table, the
location must be placed in TBLP. The TBLH
is read only and cannot be restored. If the
