Pointer Designation
When an address is passed to a function as a parameter, this is referred to as pointer designa-
tion. When pointer designation is used, the continuous data area starting from the address of the
specified register address can be used in internal processing for functions with all data types.

Data Types and Register Designations
Integer data
Bit data
Address data
An extra digit that species the bit (3) is appended
to the end of the register address (0000100).
One word is allocated for each register address.
Double-length integer or
real number data type
Bit data
If MA0000101 is specied as a pointer, it addresses
a continuous data area with the specied register
address (0000101) as the starting address.
This data area can be used with all data types in
internal processing for functions.
The addressed register (0000102) and the following
register (0000103) are combined as a 2-word area.
Therefore, the register addresses are specied at
intervals of 2.
