15.0
These devices have a host of features intended to max-
imize system reliability, minimize cost through elimina-
tion of external components, provide power-saving
operating modes and offer code protection:
• Reset
• Interrupts
• Watchdog Timer (WDT)
• Two-Speed Start-up
• Fail-Safe Clock Monitor
• Sleep
• Code Protection
• ID Locations
• In-Circuit Serial Programming™ (ICSP™)
There are 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 crystal
oscillator is stable. The other is the Power-up Timer
(PWRT), which provides a fixed delay of 72 ms (nomi-
nal) on power-up only. It is designed to keep the part in
Reset while the power supply stabilizes and is enabled
or disabled using a configuration bit. With these two
timers on-chip, most applications need no external
Reset circuitry.

SPECIAL FEATURES OF THE
CPU
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 or
through an interrupt.
Additional information on special features is available
in the “PICmicro
Manual” (DS33023).
15.1
The configuration bits can be programmed (read as
‘0’), or left unprogrammed (read as ‘1’), to select
various device configurations. These bits are mapped
in program memory locations 2007h and 2008h.
The user will note that address 2007h is beyond the
user program memory space which can be accessed
only during programming.
