Compare/Capture Unit (CCU)
The compare capture unit is a complex timer/register array for applications that require high
speed I/O, pulse width modulation and more timer/counter capabilities. The CCU contains
– one 16-bit timer/counter (timer 2) with 2-bit prescaler, reload capability and a max. clock
frequency of fOSC /12 (1 MHz with a 12 MHz crystal).
– one 16-bit timer (compare timer) with 8-bit prescaler, reload capability and a max. clock
frequency of fOSC/2 (6 MHz with a 12 MHz crystal).
– thirteen 16-bit compare registers.
– five of which can be used as 16-bit capture registers.
– up to 21 output lines controlled by the CCU.
– seven interrupts which can be generated by CCU-events.
Figure 5 shows a block diagram of the CCU. Eight compare registers (CM0 to CM7) can
individually be assigned to either timer 2 or the compare timer. Diagrams of the two timers are
shown in figures 6 and 7. The four compare/capture registers and the compare/reload/capture
register are always connected to timer 2. Dependent on the register type and the assigned
timer two compare modes can be selected. Table 3 illustrates possible combinations and the
corresponding output lines.
