MOVMD (W)
MOVe Multiple Data
[1] Assembly-Language Format
MOVMD.W
[2] Operation
Repeat @ER5+ → @ER6+
R4 − 1 → R4
Until R4 = 0
[3] Operand Size
Transfer data: Word
[4] Description
This instruction performs a block data transfer. Word data is consecutively transferred for each
data transfer. This instruction transfers the contents of a memory location pointed to by ER5 to a
memory location pointed to by ER6, increments the contents of ER5 and ER6 by 2, decrements
the R4 contents, and repeats these operations until R4 reaches zero. Execution then proceeds to the
next instruction. R4 contains the number of transfers to be carried out. (When setting 0 in R4, it is
considered as 65536.)
If an interrupt request occurs while the MOVMD instruction is being executed, interrupt exception
handling is carried out after the current word has been transferred. The PC value pushed on the
stack in interrupt exception handling is the address of this instruction. The remaining data
continues to be transferred after returning from the interrupt handling routine.
