Clocking - 3.2 English

There are three clock groups as follows.

• Main Clock Group (MCG). This group has the following PLLs:
  • RPU PLL
  • APU PLL
  • PMC PLL
  • NoC PLL
  • CPM4/5 PLL
• RTC Clock Group (RCG). This is a real-time clock, and a dedicated internal clock for RTC. A clock divider is not required for this clock.
• Interface Clock Group (ICG). This group has clocks that are provided externally, like the clocks from the physical-side interface (PHY) and PL.
