XMEGA B [DATASHEET]
8291B–AVR–01/2013
4.16 Register Description – Production Signature Row
4.16.1 RCOSC2M – Internal 2MHz Oscillator Calibration register
Bit 7:0 – RCOSC2M[7:0]: Internal 2MHz Oscillator Calibration Value
This byte contains the oscillator calibration value for the internal 2MHz oscillator. Calibration of the oscillator is performed
during production testing of the device. During reset, this value is automatically loaded into calibration register B for the
2MHz DFLL. Refer to “CALB – Calibration register B” on page 94 for more details.
4.16.2 RCOSC2MA – Internal 2MHz Oscillator Calibration register
Bit 7:0 – RCOSC2MA[7:0]: Internal 2MHz Oscillator Calibration Value
This byte contains the oscillator calibration value for the internal 2MHz oscillator. Calibration of the oscillator is performed
during production testing of the device. During reset, this value is automatically loaded into calibration register A for the
2MHz DFLL. Refer to “CALA – Calibration register A” on page 93 for more details.
4.16.3 RCOSC32K – Internal 32.768kHz Oscillator Calibration register
Bit 7:0 – RCOSC32K[7:0]: Internal 32.768kHz Oscillator Calibration Value
This byte contains the oscillator calibration value for the internal 32.768kHz oscillator. Calibration of the oscillator is
performed during production testing of the device. During reset, this value is automatically loaded into the calibration
register for the 32.768kHz oscillator. Refer to “RC32KCAL – 32kHz Oscillator Calibration register” on page 92 for more
details.
4.16.4 RCOSC32M – Internal 32MHz Oscillator Calibration register
Bit 7:0 – RCOSC32M[7:0]: Internal 32MHz Oscillator Calibration Value
This byte contains the oscillator calibration value for the internal 32MHz oscillator. Calibration of the oscillator is
performed during production testing of the device. During reset, this value is automatically loaded into calibration register
B for the 32MHz DFLL. Refer to “CALB – Calibration register B” on page 94 for more details.
