Notes on EEPMOV Instruction
1. The EEPMOV instruction is a block data transfer instruction. It moves the number of bytes
2. When setting R4L and R6, make sure that the final destination address (R6 + R4L) does not
3.6 CPU States
The CPU has three states: the program execution state, exception-handling state, and power-down
state. The power-down state is further divided into three modes: the sleep mode, software standby
mode, and hardware standby mode. Figure 3-11 summarizes these states, and figure 3-12 shows a
map of the state transitions.

exceed H'FFFF. The value in R6 must not change from H'FFFF to H'0000 during execution of
the instruction.

Program execution state
Exception-handling state
Power-down state
The CPU executes successive program instructions.
A transient state triggered by a reset or interrupt. The CPU executes a hardware
sequence that includes loading the program counter from the vector table.
A state in which some or all of the chip
functions are stopped to conserve power.
