Cpmpare / Capture Unit (CCU)
The compare/capture unit is one of the
C517A’s most powerful peripheral units for use in all kinds
of digital signal generation and event capturing like pulse generation, pulse width modulation, pulse
width measuring etc. The CCU consists of two 16-bit timer/counters with automatic reload feature
and an array of 13 compare or compare/capture registers. A set of six control registers is used for
flexible adapting of the CCU to a wide variety of user’s applications.
The block diagram in
figure 11
shows the general configuration of the CCU. All CC1 to CC4
registers and the CRC register are exclusively assigned to timer 2. Each of the eight compare
registers CM0 through CM7 can either be assigned to timer 2 or to the faster compare timer, e.g. to
provide up to 8 PWM output channels. The assignment of the CMx registers - which can be done
individually for every single register - is combined with an automatic selection of one of the two
possible compare modes.
