7 The Timer/Counter Unit (TCU) in Ingenic JZ47xx SoCs is a multi-function
11 - JZ4725B, JZ4750, JZ4755 only have six TCU channels. The other SoCs all
14 - JZ4725B introduced a separate channel, called Operating System Timer
15 (OST). It is a 32-bit programmable timer. On JZ4760B and above, it is
16 64-bit.
18 - Each one of the TCU channels has its own clock, which can be reparented to three
21 - The watchdog and OST hardware blocks also feature a TCSR register with the same
23 - The TCU registers used to gate/ungate can also gate/ungate the watchdog and
24 OST clocks.
