9.0
The PIC16F716 device has a host of features intended
to maximize system reliability, minimize cost through
elimination of external components, provide power
saving operating modes and offer code protection.
These are:
• OSC Selection
• Reset
• Interrupts
• Watchdog Timer (WDT)
• Sleep
• Code protection
• ID locations
• In-Circuit Serial Programming™ (ICSP™)
The PIC16F716 device has a Watchdog Timer, which
can be shut off only through configuration bits. It runs
off its own RC oscillator for added reliability. 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 on power-up only and is
designed to keep the part in Reset while the power
supply stabilizes. With these two timers on-chip, most
applications need no external Reset circuitry.
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. Several oscillator options are also
made available to allow the part to fit the application.
The RC oscillator option saves system cost, while the
LP crystal option saves power. A set of configuration
bits are used to select various options.
Additional information on special features is available
in the PICmicro

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 location 2007h.
The user will note that address 2007h is beyond the
user program memory space. In fact, it belongs to the
special configuration memory space (2000h – 3FFFh),
which can be accessed only during programming.
