SPECIAL FEATURES OF THE

CPU

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

- Power-on Reset (POR)

- Power-up Timer (PWRT)

- Oscillator Start-up Timer (OST)

- Brown-out Reset (BOR)

• 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® Mid-Range Reference Manual,

(DS33023).

Configuration Bits

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.
