Programcounter
-
PC
This counter addresses the program ROM and
is arranged as a 12-bit binary counter from PC0
to PC11 of which contents specify a maximum
of 4096 addresses. The program counter counts
with an increment of 1 or 2 with each execution
ofaninstruction.
When executing the jump instruction (JMP, JNZ,
JC, JTMR,...), a subroutine call, initial reset, in-
ternal interrupt, external interrupt or returning
from a subroutine, the program counter is loaded
withthecorrespondinginstructiondataasshown
in the table.

Programmemory

ROM
Theprogrammemoryistheexecutablememory
and is arranged in a 4096
′
8 bit format. The ad-
dress is specified by the program counter (PC).
Four special locations are reserved and de-
scribedasfollows:
·
Location0
Activating the processor RES pin causes the
firstinstructiontobefetchedfromlocation0.
·
Location4
Contains the timer interrupt resulting from a
TIMER overflow. If the interrupts are enabled
itcausestheprogramtojumptothissubroutine.
·
Location8
Activating the INT input pin of the processor
with the interrupts enabled causes the pro-
gramtojumptothislocation.
Activating the PS, PP or PM input pins of the
processor with the interrupts enabled during
Halt mode also causes the program to jump to
thislocation.
·
Locationsn00HtonFFH
These are the 256 bytes of each page in the pro-
gram memory. This area from n00H to nFFH
andF00HtoFFFHcanbeusedasalook upta-
ble. Instructions such as READ R4A, READ
MR0A, READF R4A, READF MR0A can read
the table and transfer the contents of the table
to ACC and R4 or to ACC and a data memory
address specified by the register pair R1,R0.
However as R1,R0 can only store 8 bits, these
instructions cannot fully specify the full 12 bit
