Effects of Sleep Mode on the
On-Chip Oscillator
When the device executes a SLEEP instruction, the on-
chip clocks and oscillator are turned off and the device
is held at the beginning of an instruction cycle (Q1
state). With the oscillator off, the OSC1 and OSC2
signals will stop oscillating. Since all the transistor
switching currents have been removed, Sleep mode
achieves the lowest current consumption of the device
(only leakage currents). Enabling any on-chip feature
that will operate during Sleep will increase the current
consumed during Sleep. The user can wake from
Sleep through external Reset, Watchdog Timer Reset
or through an interrupt.
2.8
Power-up Delays
Power up delays are controlled by two timers so that no
external
Reset
circuitry
is
required
for
most
applications. The delays ensure that the device is kept
in Reset until the device power supply and clock are
stable. For additional information on Reset operation,
The first timer is the Power-up Timer (PWRT), which
optionally provides a fixed delay of 72 ms (nominal) on
power-up only (POR and BOR). The second timer is
the Oscillator Start-up Timer (OST), intended to keep
the chip in Reset until the crystal oscillator is stable.
With the PLL enabled (HS/PLL Oscillator mode), the
time-out sequence following a Power-on Reset is differ-
ent from other oscillator modes. The time-out sequence
is as follows: First, the PWRT time-out is invoked after
a POR time delay has expired. Then, the Oscillator
Start-up Timer (OST) is invoked. However, this is still
not a sufficient amount of time to allow the PLL to lock
at high frequencies. The PWRT timer is used to provide
an additional fixed 2 ms (nominal) time-out to allow the
PLL ample time to lock to the incoming clock frequency.
