EEPMOV (MOVe data to EEPROM)
This instruction performs a block data transfer. It moves data from the memory location specified
in ER5 to the memory location specified in ER6, increments ER5 and ER6, decrements R4L, and
repeats these operations until R4L reaches zero. Execution then proceeds to the next instruction.
The data transfer is performed a byte at a time, with R4L indicating the number of bytes to be
transferred. The byte symbol in the assembly-language format designates the size of R4L (and
limits the maximum number of bytes that can be transferred to 255). No interrupts are detected
while the block transfer is in progress.
When the EEPMOV.B instruction ends, R4L contains 0 (zero), and ER5 and ER6 contain the last
transfer address + 1.
Operand Format and Number of States Required for Execution
Note: * n is the initial value of R4L. Although n bytes of data are transferred, 2(n + 1) data accesses are
This instruction first reads the memory locations indicated by ER5 and ER6, then carries out the
block data transfer.
