                                      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.
