                                      int wordcount)

Constructs a new WriteMultipleRegistersResponse instance.

Parameters:

reference - the offset to start reading from.

wordcount - the number of words (registers) to be read.

Method Detail

getReference

public int getReference()

Returns the reference of the register to start writing to with this WriteMultipleRegistersResponse.

Returns:

the reference of the register to start writing to as int.
