Register Description - Production Signature Row
RCOSC2M - Internal 2 MHz Oscillator Calibration Register
RCOSC32K - Internal 32.768 kHz Oscillator Calibration Register
RCOSC32M - Internal 32 MHz RC Oscillator Calibration Register
• Bit 7:0 - RCOSC2M[7:0]: Internal 2 MHz Oscillator Calibration Value
This byte contains the oscillator calibration value for the internal 2 MHz oscillator. Calibration of
the oscillator is performed during production test of the device. During reset this value is auto-
matically loaded into the Calibration Register B for the 2 MHz DFLL, refer to
Register B” on page 92
• Bit 7:0 - RCOSC32K[7:0]: Internal 32 kHz Oscillator Calibration Value
This byte contains the oscillator calibration value for the internal 32.768 kHz oscillator. Calibra-
tion of the oscillator is performed during production test of the device. During reset this value is
automatically loaded into the calibration register for the 32.768 kHz oscillator, refer to
”RC32KCAL - 32 KHz Oscillator Calibration Register” on page 90
• Bit 7:0 - RCOSC32M[7:0]: Internal 32 MHz Oscillator Calibration Value
This byte contains the oscillator calibration value for the internal 32 MHz oscillator. Calibration of
the oscillator is performed during production test of the device. During reset this value is auto-
matically loaded into the Calibration Register B for the 32 MHz DFLL, refer to
Calibration Register B” on page 92
