Calibration Byte
Page Size
Table 27-10. Device ID
The ATmega48A/48PA/88A/88PA/168A/168PA/328/328P has a byte calibration value for the
Internal RC Oscillator. This byte resides in the high byte of address 0x000 in the signature
address space. During reset, this byte is automatically written into the OSCCAL Register to
ensure correct frequency of the calibrated RC Oscillator.
