Register Description - DFLL32M/DFLL2M
CTRL - DFLL Control Register
CALA - Calibration Register A
CALB - Calibration Register B
• Bit 7:1 - Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bit 0 - ENABLE: DFLL Enable
Setting this bit enables the DFLL and auto-calibration of the internal oscillator
CALA and CALB register holds the 13 bit DFLL calibration value that is used for automatic run-
time calibration the internal oscillator. When the DFLL is disabled, the calibration registers can
be written by software for manual run-time calibration of the oscillator. The oscillators will be cal-
ibrated according to the calibration value in these registers also when the DFLL is disabled.
• Bit 7:0 - CALL[7:0]: DFLL Calibration bits
These bits hold the 7 Least Significant Bits (LSB) of the calibration value for the oscillator. After
reset CALL is set to its middle value, and during automatic runtime calibration of the oscillator
these bits are use to change the oscillator frequency. The bits are controlled by the DFLL when
the DFLL is enabled.
• Bit 7:5 - Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
