12.2
The 8 MHz internal oscillator is factory calibrated.
These calibration values are stored in fuses located in
the Calibration Word (2008h). The Calibration Word is
not erased when using the specified bulk erase
sequence in the Memory Programming Specification
(DS41284) and thus, does not require reprogramming.

Some registers are not affected in any Reset condition;
their status is unknown on POR and unchanged in any
other Reset. Most other registers are reset to a “Reset
state” on:

WDT wake-up does not cause register resets in the
same manner as a WDT Reset since wake-up is
viewed as the resumption of normal operation. TO and
PD bits are set or cleared differently in different Reset
situations, as indicated in Table 12-2. Software can use
these bits to determine the nature of the Reset. See
Table 12-4 for a full description of Reset states of all
registers.
A simplified block diagram of the On-Chip Reset Circuit
is shown in Figure 12-1.
The MCLR Reset path has a noise filter to detect and
ignore small pulses. See Section 15.0 “Electrical
Specifications” for pulse-width specifications.
