electrical characteristics (if a quartz crystal is used), as well as any other external circuitry
(e.g., capacitors), and the characteristics of the oscillator itself under the existing ambient
conditions.

Power control
The LPC1759/58/56/54/52/51 support a variety of power control features. There are four
special modes of processor power reduction: Sleep mode, Deep-sleep mode,
Power-down mode, and Deep power-down mode. The CPU clock rate may also be
controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering
the CPU clock divider value. This allows a trade-off of power versus processing speed
based on application requirements. In addition, Peripheral Power Control allows shutting
down the clocks to individual on-chip peripherals, allowing fine tuning of power
consumption by eliminating all dynamic power use in any peripherals that are not required
for the application. Each of the peripherals has its own clock divider which provides even
better power control.
Integrated PMU (Power Management Unit) automatically adjust internal regulators to
minimize power consumption during Sleep, Deep sleep, Power-down, and Deep
power-down modes.
The LPC1759/58/56/54/52/51 also implement a separate power domain to allow turning
off power to the bulk of the device while maintaining operation of the RTC and a small set
of registers for storing data during any of the power-down modes.
7.29.5.1
Sleep mode
When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep
mode does not need any special sequence but re-enabling the clock to the ARM core.
In Sleep mode, execution of instructions is suspended until either a Reset or interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
7.29.5.2
Deep-sleep mode
In Deep-sleep mode, the oscillator is shut down and the chip receives no internal clocks.
The processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Deep-sleep mode and the logic levels of chip pins remain static.
The output of the IRC is disabled but the IRC is not powered down for a fast wake-up later.
The RTC oscillator is not stopped because the RTC interrupts may be used as the
wake-up source. The PLL is automatically turned off and disconnected. The CCLK and
USB clock dividers automatically get reset to zero.
The Deep-sleep mode can be terminated and normal operation resumed by either a
Reset or certain specific interrupts that are able to function without clocks. Since all
dynamic operation of the chip is suspended, Deep-sleep mode reduces chip power
consumption to a very low value. Power to the flash memory is left on in Deep-sleep
mode, allowing a very quick wake-up.
