[4] Description
This instruction performs a block data transfer. It moves data from a memory location specified in
ER5 to a memory location specified in ER6, increments ER5 and ER6, decrements R4, and
repeats these operations until R4 reaches zero. Execution then proceeds to the next instruction.
Byte data is transferred for each transfer. R4 contains the number of bytes to be transferred. The
word symbol (W) in the assembly-language format above designates a 16-bit register R4 used in
this instruction to indicate the amount of transfer data (allowing a maximum 65535 bytes to be
transferred). All interrupts are detected while the block transfer is in progress.
If no interrupt occurs while the EEPMOV.W instruction is executing, R4 contains 0 (zero), and
ER5 and ER6 contain the last transfer address + 1 when the EEPMOV.W instruction ends. If an
interrupt occurs, interrupt exception handling begins after the current byte has been transferred. At
this time, R4 indicates the number of bytes remaining to be transferred. ER5 and ER6 indicate the
next transfer addresses. The PC value pushed onto the stack in interrupt exception handling is the
start address of the instruction immediately after the EEPMOV.W instruction.
