(8) Program counter (PC)
Program counter (PC) is used to specify a ROM address (page
and address). It determines a sequence in which instructions
stored in ROM are read. It is a binary counter that increments
the number of instruction bytes each time an instruction is
executed. However, the value changes to a specified address
when branch instructions, subroutine call instructions, return
instructions, or the table reference instruction (TABP p) is
executed.
Program counter consists of PC
H
(most significant bit to bit 7)
which specifies to a ROM page and PC
L
(bits 6 to 0) which
specifies an address within a page. After it reaches the last
address (address 127) of a page, it specifies address 0 of the
next page (Figure 7).
Make sure that the PC
H
does not exceed after the last page of
the built-in ROM.
(9) Data pointer (DP)
Data pointer (DP) is used to specify a RAM address and
consists of registers X and Y. Register X specifies a file and
register Y specifies a RAM digit (Figure 8).
Register Y is also used to specify the port D bit position.
When using port D, set the port D bit position to register Y
certainly and execute the SD, RD, or SZD instruction (Figure
9).
