Register Description
Oscillator Calibration Register
– OSCCAL
Bits 7..0 – CAL7..CAL0: Oscillator Calibration Value
Writing the calibration byte to this address will trim the internal oscillator to remove pro-
cess variation from the oscillator frequency. When OSCCAL is zero, the lowest available
frequency is chosen. Writing non-zero values to the register will increase the frequency
to the internal oscillator. Writing $FF to the register gives the highest available fre-
quency. Table 2 shows the range for OSCCAL. Note that the oscillator is intended for
calibration to 1.2 MHz, thus tuning to other values is not guaranteed. At 3V and 25
oC,
the pre-programmed calibration byte gives a frequency within ± 1% of the nominal
frequency.
