Description

The contents of the specified data-memory address are copied into the con-

tents of the next higher address. When data is copied from the addressed loca-

tion to the next higher location, the contents of the addressed location remain

unaltered.

DMOV works only within on-chip data DARAM blocks. It works within any con-

figurable RAM block if that block is configured as data memory. In addition, the

data move function is continuous across block boundaries. The data move

function cannot be performed on external data memory. If the instruction spec-

ifies an external memory address, DMOV reads the specified memory location

but performs

no operations.

The data move function is useful in implementing the z–1 delay encountered

in digital signal processing. The DMOV function is a subtask of the LTD and

MACD instructions (see the LTD and MACD instructions for more information).
