2. Internal CPU Function
2.1 Program Counter (PC)
The program counter is a 11-bit binary counter which indicates
the address of the program memory storing the next instruc-
tion to be executed.Normally, the PC is incremented by the
number of bytes of the instruction every time it is fetched.
When a branch instruction or a subroutine instruction has been
executed or an interrupt has been accepted, the specified val-
ues listed in Table 2-1 are set to the PC. The PC is initialized to
“0” during reset.
Figure 2-1. Configuration of Program Counter
The PC can directly address a 2048-byte address space.
However, with the short branch, the following points must be
considered:
• Short branch instruction [BSS a]
In [BSS a] instruction execution, when the branch con-
dition is satisfied, the value specified in the instruction
is set to the lower 6 bits of the PC.That is, [BSS a]
becomes the in-page branch instruction. When [BSS
a] is stored at the last address of the page, the upper 5
bits of the PC point the next page, so that branch is
made to the next page.

2.2 Program Memory (ROM)
Programs and fixed data are stored in the program memory.
The instruction to be executed next is read from the address
indicated by the contents of the PC.
The fixed data can be read by using the table look-up in-
structions.
• Table look-up instructions
[LDL A, @DC], [LDH A, @DC+]
The table look-up instructions read the lower and
upper 4 bits of the fixed data stored at the address
specified in the data counter (DC) to place them into
the accumulator. [LDL A, @DC] instruction reads the
lower 4 bits of fixed data, and [LDH A, @DC+] instruc-
tion reads the upper 4 bits.
The DC is a 12-bit register, allowing it to address the
entire program memory space.
Example: When [LDL A, @DC] instruction is executed
with the DC value being 7AO
H
being 58
H
,
“8” is stored in the accumulator; when [LDH
A, @DC+] instruction is executed, “5” is
stored in the accumulator and the DC value
is incremented to 7A1
H
.

is accessed by program, the most significant bit of each
address is always regarded as “0” and the contents of the pro-
gram memory corresponding to the address is always
regarded as “0” and the contents of the program memory cor-
