SPECIAL FEATURES OF THE
CPU
The PIC12F683 has a host of features intended to
maximize system reliability, minimize cost through
elimination of external components, provide power
saving features and offer code protection.
These features are:
Reset
- Power-on Reset (POR)
- Power-up Timer (PWRT)
- Oscillator Start-up Timer (OST)
- Brown-out Reset (BOR)
Interrupts
Watchdog Timer (WDT)
Oscillator Selection
Sleep
Code Protection
ID Locations
In-Circuit Serial Programming
The PIC12F683 has two timers that offer necessary
delays on power-up. One is the Oscillator Start-up Timer
(OST), intended to keep the chip in Reset until the crys-
tal oscillator is stable. The other is the Power-up Timer
(PWRT), which provides a fixed delay of 64 ms (nomi-
nal) on power-up only, designed to keep the part in
Reset while the power supply stabilizes. There is also
circuitry to reset the device if a brown-out occurs, which
can use the Power-up Timer to provide at least a 64 ms
Reset. With these three functions on-chip, most
applications need no external Reset circuitry.
The Sleep mode is designed to offer a very low-current
Power-down mode. The user can wake-up from Sleep
through:
External Reset
Watchdog Timer Wake-up
An interrupt
Several oscillator options are also made available to
allow the part to fit the application. The INTOSC option
saves system cost while the LP crystal option saves
power. A set of Configuration bits are used to select
various options (see Register 12-1).
12.1
Configuration Bits
The Configuration bits can be programmed (read as
‘0’), or left unprogrammed (read as ‘1’) to select various
device configurations as shown in Register 12-1.
These bits are mapped in program memory location
2007h.
Note:
Address
2007h is
beyond the user
program memory space. It belongs to the
special
configuration
memory
space
(2000h-3FFFh), which can be accessed
only
during
programming.

ming Specification” (DS41204) for more
