Description
Command Code bits 4 through 0
These bits specify the command code of the special function if the control
code is 000. Table 4-4 is a summary of the implemented special
functions. Table 4-5 explains the details of each special function. If the
control code is not 000, then these bits are written to one of the hidden
registers (indicated by the control code in CNT[2-0]).
