The internal shift register in the CX24109 is 21 bits long. When the data is latched into the IC,
the two MSBs act as control bits, and the lower 19 bits are the data bits as illustrated in
Figure
The control bits determine the functional block that is being programmed, while the data bits
contain the specific control information.
