6.8.1.8
In this mode the result of an operation between two registers is stored in one of the registers used as
operands.
RD = RD RS is the general register to register format, with register RD being the first operand and RS
the second. RD and RS can be any of the 8 general purpose registers R0 … R7. If R0 is used as the
destination register, only the condition code flags are updated. This addressing mode is used only for shift
operations with a variable shift value
Examples:
6.8.1.9
In this mode the result of an operation between two or three registers is stored into a third one.
RD = RS1 RS2 is the general format used in the order RD, RS1, RS1. RD, RS1, RS2 can be any of the
8 general purpose registers R0 … R7. If R0 is used as the destination register RD, only the condition code
flags are updated. This addressing mode is used for all arithmetic and logical operations.
Examples:
6.8.1.10
A 9-bit signed word address offset is included in the instruction word. This addressing mode is used for
conditional branch instructions.
Examples:
6.8.1.11
An 11-bit signed word address offset is included in the instruction word. This addressing mode is used for
the unconditional branch instruction.
Examples:
6.8.1.12
(RS, #offset5) provides an unsigned offset from the base register.
