12.2
The Brown-out Detect (BOD), Power-on Reset (POR)
and 8 MHz internal oscillator (INTOSC) are factory
calibrated. These calibration values are stored in the
calibration word, as shown in Register 12-2 and are
mapped in program memory location 2008h.
The calibration word is not erased when the device is
erased when using the procedure described in the
PIC12F683 Programming Specification. Therefore, it
is not necessary to store and reprogram these values
when the device is erased.

Calibration Bits
This location does not participate in bulk erase operations if the PIC12F683 Programming Specification
procedure is used.
Calibration bits are reserved for factory calibration. These values can and will change across the entire
range, therefore, specific values and available adjustment range can not be specified.
