This 8 bit register selects the Deactivate code sequence that is to be detected. If
the code sequence length is less than 8 bits, the first 8 bits of several repetitions
of the code sequence must be used to fill the 8 bit register. For example, if code
sequence is a repeating 001, then the first 8 bits of three repetitions (001001001)
is programmed into the register (i.e. 00100100). Note that bit DACT7 corresponds
to the first code bit received.
