SFR
The SFRs can only be addressed directly in the
address range from 80h to FFh. Table 15, page 31
gives an overview of the Special Function Regis-
ters. Sixteen address in the SFRs space are both-
byte and bit-addressable. The bit-addressable
SFRs are those whose address ends in 0h and 8h.
The bit addresses in this area are 80h to FFh.
Table 3. RAM Address
Addressing Modes
The addressing modes in uPSD321X Devices in-
struction set are as follows
Direct addressing
Indirect addressing
Register addressing
Register-specific addressing
Immediate constants addressing
Indexed addressing

(1) Direct addressing.
In a direct addressing the
operand is specified by an 8-bit address field in the
instruction. Only internal Data RAM and SFRs
(80~FFH RAM) can be directly addressed.
Example:
mov A, 3EH ;A <----- RAM[3E]
Figure 10. Direct Addressing
(2) Indirect addressing.
In indirect addressing
the instruction specifies a register which contains
the address of the operand. Both internal and ex-
ternal RAM can be indirectly addressed. The ad-
dress register for 8-bit addresses can be R0 or R1
of the selected register bank, or the Stack Pointer.
The address register for 16-bit addresses can only
be the 16-bit “data pointer” register, DPTR.
Example:
mov @R1, #40 H ;[R1] <-----40H
