SPECIAL FEATURES OF THE
CPU
The PIC16F610/616/16HV610/616 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 PIC16F610/616/16HV610/616 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 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. See the Memory Program-
ming Specification (DS41284) for more
information.
