Module features

2.4.1

Low-power operation

PXD10 devices are designed for optimized low-power operation and dynamic power management of the

core processor and peripherals. Power management features include software-controlled clock gating of

peripherals and multiple power domains to minimize leakage in low-power modes.

There are two static low-power modes, STANDBY and STOP, and two dynamic power modes—RUN and

HALT. Both low power modes use clock gating to halt the clock for all or part of the device. The

STANDBY mode also uses power gating to automatically turn off the power supply to parts of the device

to minimize leakage.

STANDBY mode turns off the power to the majority of the chip to offer the lowest power consumption

mode. The contents of the cores, on-chip peripheral registers and potentially some of the volatile memory

are lost. STANDBY mode is configurable to make certain features available with the disadvantage that

these consume additional current:

•

It is possible to retain the contents of the full RAM or only 8 KB.

It is possible to enable the internal 16 MHz or 128 kHz RC oscillator, the external 4–16 MHz

oscillator, or the external 32 KHz oscillator.

•

It is possible to keep the LCD module active.

The device can be awakened from STANDBY mode via from any of up to 19 I/O pins, a reset or from a

periodic wake-up using a low power oscillator.

STOP mode maintains power to the entire device allowing the retention of all on-chip registers and

memory, and providing a faster recovery low power mode than the lowest STANDBY mode. There is no

need to reconfigure the device before executing code. The clocks to the core and peripherals are halted and

can be optionally stopped to the oscillator or PLL at the expense of a slower start-up time.

STOP is entered from RUN mode only. Wake-up from STOP mode is triggered by an external event or by

the internal periodic wake-up, if enabled.

RUN modes are the main operating mode where the entire device can be powered and clocked and from

which most processing activity is done. Four dynamic RUN modes are supported—RUN0 - RUN3. The

ability to configure and select different RUN modes enables different clocks and power configurations to

be supported with respect to each other and to allow switching between different operating conditions. The
