Figure 7-42 and 7-43 show the general timer/compare register/port latch configuration for registers
CRC and CC1 to CC4 in compare mode 0 and compare mode 1. Please note that the compare
interrupts of registers CRC and CC4 can be programmed to be negative or positive transition
activated. Compare interrupts for the CC1 to CC3 registers are always positive transition activated.
