General Register (GR)
A general register is a 16-word register on the data memory and used for arithmetic operations and transfer of
data to and from the data memory.
(1) Configuration of general register
Figure 4-7 shows the configuration of the general register.
A general register occupies 16 nibbles (16 x 4 bits) on a selected row address of the data memory.
The row address is selected by the general register pointer (RP) of the system register. The RP having five
significant bits can point to any row address in the range of 0H to 7H of each bank (BANK0 to BANK2).
(2) Functions of the general register
The general register enables an arithmetic operation and data transfer between the data memory and a
selected general register by a single instruction. As a general register is a part of the data memory, you can
say that the general register enables arithmetic operation and data transfer between two locations of the data
memory. Similarly, the general register can be accessed by a Data Memory Manipulation instruction as it is
a part of the data memory.
