Effects of Power-Managed Modes
on the Various Clock Sources
When PRI_IDLE mode is selected, the designated
primary oscillator continues to run without interruption.
For all other power-managed modes, the oscillator
using the OSC1 pin is disabled. The OSC1 pin (and
OSC2 pin if used by the oscillator) will stop oscillating.
In
secondary
clock
modes
(SEC_RUN
and
SEC_IDLE), the Timer1 oscillator is operating and
providing the device clock. The Timer1 oscillator may
also run in all power-managed modes if required to
clock Timer1 or Timer3.
In RC_RUN and RC_IDLE modes, the internal oscilla-
tor provides the device clock source. The 31 kHz
INTRC output can be used directly to provide the clock
and may be enabled to support various special
features, regardless of the power-managed mode (see
information on WDT, Fail-Safe Clock Monitor and
Two-Speed Start-up).
If the Sleep mode is selected, all clock sources are
stopped. Since all the transistor switching currents
have been stopped, 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 INTRC is required to support WDT operation. The
Timer1 oscillator may be operating to support a
Real-Time Clock. Other features may be operating that
do not require a device clock source (i.e., MSSP slave,
PSP, INTx pins and others). Peripherals that may add
significant
current
consumption
are
listed
in
Section 27.2 “DC Characteristics: Power-Down and
Supply Current”.
3.8
Power-up Delays
Power-up delays are controlled by two timers, so that
no external Reset circuitry is required for most applica-
tions. The delays ensure that the device is kept in
Reset until the device power supply is stable under
normal circumstances and the primary clock is operat-
ing and stable. For additional information on power-up
delays, see Section 5.5 “Power-up Timer (PWRT)”.
The first timer is the Power-up Timer (PWRT), which
provides a fixed delay on power-up (parameter 33,
Table 27-12). It is always enabled.
The second timer is the Oscillator Start-up Timer
(OST), intended to keep the chip in Reset until the
crystal oscillator is stable (HS modes). The OST does
this by counting 1024 oscillator cycles before allowing
the oscillator to clock the device.
There is a delay of interval, TCSD (parameter 38,
Table 27-12), following POR, while the controller
becomes ready to execute instructions.
