12.2
The Brown-out Detect (BOD), Power-on Reset (POR)
and 8 MHz internal oscillator (HFINTOSC) are factory
calibrated. These calibration values are stored in the
Calibration Word register, as shown in Register 12-2
and are mapped in program memory location 2008h.
The Calibration Word register is not erased when the
device is erased when using the procedure described
in the “PIC12F6XX/16F6XX Memory Programming
Specification”
necessary to store and reprogram these values when
the device is erased.
