18 - Each one of the TCU channels has its own clock, which can be reparented to three
23 - The TCU registers used to gate/ungate can also gate/ungate the watchdog and
26 - Each TCU channel works in one of two modes:
33 - The mode of each TCU channel depends on the SoC used:
55 The functionalities of the TCU hardware are spread across multiple drivers:
