11.3.4
BROWN-OUT RESET (BOR)
The BOREN0 and BOREN1 bits in the Configuration
Word register select one of three BOR modes. One
mode has been added to allow control of the BOR
enable for lower current during Sleep. By selecting
BOREN<1:0> =
10
, the BOR is automatically disabled
in Sleep to conserve power and enabled on wake-up.
See Register 11-1 for the Configuration Word
definition.
A brown-out occurs when V
DD
falls below V
BOR
for
greater than parameter T
BOR
(see
Section 15.0
“Electrical Specifications”
). The brown-out condition
will reset the device. This will occur regardless of V
DD
slew rate. A Brown-out Reset may not occur if V
DD
falls
below V
BOR
for less than parameter T
BOR
.
On any Reset (Power-on, Brown-out Reset, Watchdog
timer, etc.), the chip will remain in Reset until V
DD
rises
above V
BOR
(see Figure 11-3). If enabled, the Power-
up Timer will be invoked by the Reset and keep the chip
in Reset an additional 64 ms.
If V
DD
drops below V
BOR
while the Power-up Timer is
running, the chip will go back into a Brown-out Reset
and the Power-up Timer will be re-initialized. Once V
DD
rises above V
BOR
, the Power-up Timer will execute a
64 ms Reset.
11.3.5
BOR CALIBRATION
The PIC12F609/615/12HV609/615 stores the BOR
calibration values in fuses located in the Calibration
Word register (2008h). The Calibration Word register is
not erased when using the specified bulk erase
sequence in the “
PIC12F6XX/16F6XX Memory Pro-
gramming Specification
” (DS41204) and thus, does not
require reprogramming.
FIGURE 11-3:
BROWN-OUT SITUATIONS
Note:
The Power-up Timer is enabled by the
PWRTE bit in the Configuration Word
register.
Note:
Address 2008h is beyond the user pro-
gram memory space. It belongs to the
special configuration memory space
(2000h-3FFFh), which can be accessed
only
during
programming.

ming Specification”
