Section 1 CPU
H'00001001.
After execution, ER0 is H'00001002.
Example 3:
XOR.B
R0L, @ER0+
When the value in ER0 before execution is H'00001234, location H'00001234 is read, the read
data is EORed with H'35, and the result is written to location H'00001234.
The value in ER0 after execution is H'00001235.
1.8.6
Absolute Address—@aa:8, @aa:16, @aa:24, or @aa:32
The operand value is the contents of a memory location which is pointed to by an absolute address
included in the instruction code.
There are 8-bit (@aa:8), 16-bit (@aa:16), 24-bit (@aa:24), and 32-bit (@aa:32) absolute
addresses.
To access the data area, the absolute address of 8 bits (@aa:8), 16 bits (@aa:16), or 32 bits
(@aa:32) is used. For an 8-bit absolute address, the upper 24 bits are specified by SBR. For a 16-
bit absolute address, the upper 16 bits are sign-extended. A 32-bit absolute address can access the
entire address space.
To access the program area, the absolute address of 24 bits (@aa:24) or 32 bits (@aa:32) is used.
For a 24-bit absolute address, the upper 8 bits are all assumed to be 0 (H'00).
Table 1.13 shows the accessible absolute address ranges.
