Standard Type TM Register Description
Overall operation of the Standard TM is controlled using a series of registers. A read only register
pair exists to store the internal counter 10 or 16-bit value, while a read/write register pair exists to
store the internal 10 or 16-bit CCRA value. The remaining two registers are control registers which
setup the different operating and control modes as well as the three or eight CCRP bits.
