PRELIMINARY INFORMATION AUG 02, 2011
Table 6.3.4.1: Constant Generation Register CG1/CG2 Table
The assembler uses the constant generator automatically if one of the six constants is used as an immediate
source operand. Registers R2 and R3, used in the constant mode, cannot be addressed explicitly; they act as
source-only registers.
registers, address pointers, or index values and can be accessed with byte or word instructions.
Seven addressing modes for the source operand and four addressing modes for the destination operand can
address the complete address space with no exceptions. The bit numbers in the table below describe the
contents of the As(source) and Ad (destination) mode bits.

Description
Register contents are operand
(Rn + X) point to the operand. Xis stored
in the next word
(Rn + X) point to the operand. Xis stored
in the next word. Indexed mode X(PC) is
used.
The word following the instruction con-
tains the absolute address. X
is stored in the next word. Indexed
mode X(SR) is used.
Rn is used as a pointer to the
operand.
Rn is used as a pointer to the operand.
Rn is incremented afterwards by 1 for .B
instructions and by 2 for .W instructions.
