The Renesas RZ/N1 timer block controller is the controller in charge of
timers available in the Renesas RZ/N1 SoCs family.
This controller handles 8 timers:
- 6 16-bit timers
- 2 32-bit timers
Each timer has its own interrupt, its own prescaler that can be used to
device the clock by 25 and all of them can work in either one-shot or
periodic mode.

In the Renesas RZ/N1 SoCs family, two timers block are available.
Each block contains 8 timers composed of 6 16-bits timers and 2 32-bits
timers.
Each timer has its own interrupt line.
Describe those timers blocks.
