TnPAU
Overall operation of the Compact TM is controlled using six registers. A read only register pair exists
to store the internal counter 10-bit value, while a read/write register pair exists to store the internal
10-bit CCRA value. The remaining two registers are control registers which setup the different
operating and control modes as well as the three CCRP bits.
