11.2
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, as shown in Register 11-2 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
“PIC12F6XX/16F6XX
Specification”
necessary to store and reprogram these values when
the device is erased.
