SPECIAL FEATURES OF THE

CPU

The PIC12F609/615/12HV609/615 has a host of

features intended to maximize system reliability,

minimize

cost

through

elimination

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 PIC12F609/615/12HV609/615 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 crystal oscillator is stable. The

other is the Power-up Timer (PWRT), which provides a

fixed delay of 64 ms (nominal) 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 11-1).

11.1

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 11-1.

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. See “PIC12F6XX/16F6XX

Memory

Programming

Specification”

(DS41204) for more information.
