Enabling the DFLL
Internal synchronization
The DFLL can operate in both open loop mode and closed-loop mode. In closed-loop mode a
low frequency clock with high accuracy can be used as reference clock to get high accuracy on
the output clock (CLK_DFLL).
To prevent unexpected writes due to software bugs, write access to the configuration registers is
protected by a locking mechanism. For details please refer to the UNLOCK register description.
Figure 13-1. DFLLIF Block Diagram
The DFLL is enabled by writing a one to the Enable bit (EN) in the DFLLn Configuration Register
(DFLLnCONF). No other bits or fields in DFLLnCONF must be changed simultaneously, or
before the DFLL is enabled.
Due to multiple clock domains in the DFLLIF, values in the DFLLIF configuration registers need
to be synchronized to other clock domains. The status of this synchronization can be read from
the Power and Clocks Status Register (PCLKSR). Before writing to a DFLLIF configuration reg-
ister, the user must check that the DFLLn Synchronization Ready bit (DFLLnRDY) in PCLKSR is
set. When this bit is set, the DFLL can be configured, and CLK_DFLL is ready to be used. Any
write to a DFLLIF configuration register while DFLLnRDY is cleared will be ignored.
• 40-150MHz frequency
• Can operate standalone as a high-frequency programmable oscillator in open loop mode
• Can operate as an accurate frequency multiplier against a known frequency in closed-loop
• Optional spread-spectrum clock generation
• Very high-frequency multiplication supported - can generate all frequencies from a 32 KHz
