This 8 bit register selects the Activate 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 00001, then the first 8 bits of two repetitions
(0000100001) is programmed into the register (i.e. 00001000). Note that bit
ACT7 corresponds to the first code bit received.
