This LSI has an on-chip compare match timer (CMT) consisting of a two-channel 16-bit timer.
The CMT has a16-bit counter, and can generate interrupts at set intervals.

• Independent selection of four counter input clocks at two channels
• Selection of DMA transfer request or interrupt request generation on compare match by
• When not in use, the CMT can be stopped by halting its clock supply to reduce power
Figure 12.1 shows a block diagram of CMT.
