8.13.1
Idle mode
Idle mode leaves peripherals running in order to allow them to activate the processor
when an interrupt is generated. Any enabled interrupt source or reset may terminate
Idle mode.
8.13.2
Power-down mode
The Power-down mode stops the oscillator in order to minimize power consumption.
The P89LPC906/907/908 exits Power-down mode via any reset, or certain interrupts.
In Power-down mode, the power supply voltage may be reduced to the RAM
keep-alive voltage VRAM. This retains the RAM contents at the point where
Power-down mode was entered. SFR contents are not guaranteed after VDD has
been lowered to VRAM, therefore it is highly recommended to wake up the processor
via reset in this case. VDD must be raised to within the operating range before the
Power-down mode is exited.
Some chip functions continue to operate and draw power during Power-down mode,
increasing the total power used during Power-down. These include: Brownout detect,
Watchdog Timer, Comparator (Note: Comparator can be powered-down separately),
and Real-Time Clock (RTC)/System Timer. The internal RC oscillator is disabled
unless both the RC oscillator has been selected as the system clock and the RTC is
enabled.
8.13.3
Total Power-down mode
This is the same as Power-down mode except that the brownout detection circuitry
and the voltage comparators are also disabled to conserve additional power. The
internal RC oscillator is disabled unless both the RC oscillator has been selected as
the system clock and the RTC is enabled. If the internal RC oscillator is used to clock
the RTC during Power-down, there will be high power consumption. Please use an
external low frequency clock to achieve low power with the Real-Time Clock running
during Power-down.
8.14 Reset
The P1.5/RST pin can function as either an active-LOW reset input or as a digital
input, P1.5. The RPE (Reset Pin Enable) bit in UCFG1, when set to ‘1’, enables the
external reset input function on P1.5. When cleared, P1.5 may be used as an input
pin.
Remark: During a power-up sequence, the RPE selection is overridden and this pin
will always function as a reset input. An external circuit connected to this pin
should not hold this pin LOW during a power-on sequence as this will keep the
device in reset. After power-up this input will function either as an external reset
input or as a digital input as dened by the RPE bit. Only a power-up reset will
temporarily override the selection dened by RPE bit. Other sources of reset will not
override the RPE bit.
characteristics”) before power is reapplied, in order to ensure a power-on reset.
