The special connection between CCR0 and TR is shown in figure 12-1, if you know where to look: the output of comparator x is called EQUx, and the EQU0 signal goes into the "count mode" box. That the CCR0 has an independent interrupt vector has nothing to do with the special EQU0 handling, it's just useful to have an interrupt handler where you do not need to check which of the CCRs has triggered it. The other CCRs do not get separate interrupt vectors because that would result in too many vectors.
