9.5
On the PIC10F200/202/204/206 devices, the DRT runs
any time the device is powered up.
The DRT operates on an internal oscillator. The
processor is kept in Reset as long as the DRT is active.
The DRT delay allows V
for the oscillator to stabilize.
The on-chip DRT keeps the devices in a Reset
condition for approximately 18 ms after MCLR has
reached a logic high (V
GP3/MCLR/V
network connected to the MCLR input is not required in
most cases. This allows savings in cost-sensitive and/
or space restricted applications, as well as allowing the
use of the GP3/MCLR/V
input.
The Device Reset Time delays will vary from chip-to-
chip due to V
See AC parameters for details.
Reset sources are POR, MCLR, WDT time-out and
wake-up on pin change. See Section 9.9.2 “Wake-up
from Sleep”, Notes 1, 2 and 3.
TABLE 9-3:
9.6
The Watchdog Timer (WDT) is a free running on-chip
RC oscillator, which does not require any external
components. This RC oscillator is separate from the
internal 4 MHz oscillator. This means that the WDT will
run even if the main processor clock has been stopped,
for example, by execution of a SLEEP instruction.
During normal operation or Sleep, a WDT Reset or
wake-up Reset, generates a device Reset.
The TO bit (STATUS<4>) will be cleared upon a
Watchdog Timer Reset.
The WDT can be permanently disabled by program-
ming the configuration WDTE as a ‘0’ (see Section 9.1
“Configuration Bits”). Refer to the PIC10F200/202/
204/206 Programming Specifications to determine how
to access the Configuration Word.

The WDT has a nominal time-out period of 18 ms, (with
no prescaler). If a longer time-out period is desired, a
prescaler with a division ratio of up to 1:128 can be
assigned to the WDT (under software control) by
writing to the OPTION register. Thus, a time-out period
of a nominal 2.3 seconds can be realized. These peri-
ods vary with temperature, V

Under worst-case conditions (V

seconds before a WDT time-out occurs.
9.6.2
The CLRWDT instruction clears the WDT and the
postscaler, if assigned to the WDT, and prevents it from
timing out and generating a device Reset.
The SLEEP instruction resets the WDT and the
postscaler, if assigned to the WDT. This gives the
maximum Sleep time before a WDT wake-up Reset.
