Table 2.12 Absolute Address Access Ranges
Note:
2.7.6
The instruction code contains 8-bit (#xx:8), 16-bit (#xx:16), or 32-bit (#xx:32) immediate data as
an operand.
The ADDS, SUBS, INC, and DEC instructions contain immediate data implicitly. Some bit
manipulation instructions contain 3-bit immediate data in the instruction code, specifying a bit
number. The TRAPA instruction contains 2-bit immediate data in its instruction code, specifying a
vector address.
2.7.7
This mode is used in the Bcc and BSR instructions. An 8-bit or 16-bit displacement contained in
the instruction code is sign-extended and added to the 24-bit PC contents to generate a branch
address. Only the lower 24 bits of this branch address are valid; the upper 8 bits are all assumed to
be 0 (H'00). The PC value to which the displacement is added is the address of the first byte of the
next instruction, so the possible branching range is –126 to +128 bytes (–63 to +64 words) or –
32766 to +32768 bytes (–16383 to +16384 words) from the branch instruction. The resulting value
should be an even number.
