The PLLCTRL manages clock alignment of CBASS clocks to the peripherals in Main and MCU domains. In addition PLLCTRL is also responsible for controlling reset propagation through the chip and providing DFT hooks for testability. Two PLL Controllers are implemented in the device - PLLCTRL0 and MCU_PLLCTRL0. They are respectively related to PLL0 and MCU_PLL0.
PLLCTRL_POSTDIV is not supported in this family of devices.
The PLL Controllers registers can be accessed by any controller in the device.
A SYSCLK0 clock out of a PLLCTRL is the only synchronous clock in that domain. That means - MCU_SYSCLK0 out of MCU_PLLCTRL is the synchronous CBASS clock in MCU domain and SYSCLK0 out of Main PLLCTRL is the synchronous CBASS clock in Main domain.
