Figure 6-21 and 6-22 show the general timer/compare register/port latch configuration for registers
CRC and CC1 to CC4 in compare mode 0 and compare mode 1. It also shows the interrupt
capabilities. The compare interrupts of registers CRC and CC4 can be programmed to be either
negative or positive transition activated. Compare interrupts for the CC1 to CC3 registers are
always positive transition activated.
The compare function of CC4 is described in section 6.3.4.3.
