+title: Renesas Compare Match Timer (CMT)

+description:
+ The CMT is a multi-channel 16/32/48-bit timer/counter with configurable clock
+ inputs and programmable compare match.
+
+ Channels share hardware resources but their counter and compare match values
+ are independent. A particular CMT instance can implement only a subset of the
+ channels supported by the CMT model. Channel indices represent the hardware
+ position of the channel in the CMT and don't match the channel numbers in the
+ datasheets.
