Calibration Byte
Page Size
Table 28-10. Device ID
The ATmega48A/PA/88A/PA/168A/PA/328/P 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 fre-
quency of the calibrated RC Oscillator.
