12.2
Brown-out Reset (BOR), Power-on Reset (POR) and
8 MHz internal oscillator (HFINTOSC) are factory cali-
brated. These calibration values are stored in fuses
located in the Calibration Word (2009h). The Calibra-
tion Word is not erased when using the specified bulk
erase sequence in the “PIC12F6XX/16F6XX Memory
Programming Specification” (DS41244) and thus, does
not require reprogramming.
12.3
The PIC16F684 differentiates between various kinds of
Reset:

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:
• Power-on Reset
• MCLR Reset
• MCLR Reset during Sleep
• WDT Reset
• Brown-out Reset (BOR)
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.
