PRODUCTION DATA.
Each Concerto device contains a zero-pin internal oscillator. This oscillator outputs two fixed-frequency clocks: 10MHZCLK and 32KHZCLK. These clocks are not configurable by the user and should not be used to clock the device during normal operation. They are used inside the Master Subsystem to implement low-power modes. The 10MHZCLK is also used by the Missing Clock Detect circuit.
