User manual
3.8.1 Active mode
Reset has four sources on the LPC13xx: the RESET pin, Watchdog Reset, Power-On
Reset (POR), and Brown Out Detect (BOD). In addition, there is a software reset.
The RESET pin is a Schmitt trigger input pin. Assertion of chip Reset by any source, once
the operating voltage attains a usable level, starts the IRC causing reset to remain
asserted until the external Reset is de-asserted, the oscillator is running, and the flash
controller has completed its initialization.
On the assertion of a reset source external to the Cortex-M3 CPU (POR, BOD reset,
External reset, and Watchdog reset), following processes are initiated:
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the boot block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.
The LPC13xx includes four levels for monitoring the voltage on the V
falls below one of the four selected levels, the BOD asserts an interrupt signal to the
NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC
in order to cause a CPU interrupt; if not, software can monitor the signal by reading a
dedicated status register. An additional threshold level can be selected to cause a forced
reset of the chip.
The LPC13xx support a variety of power control features. In Active mode, when the chip is
running, power and clocks to selected peripherals can be optimized for power
consumption. In addition, there are three special modes of processor power reduction:
Sleep mode, Deep-sleep mode, and Deep power-down mode.
Remark: The Debug mode is not supported in Sleep, Deep-sleep, or Deep power-down
modes.
In Active mode, the ARM Cortex-M0 core and memories are clocked by the system clock,
and peripherals are clocked by the system clock or a dedicated peripheral clock.
The chip is in Active mode after reset and the default power configuration is determined
by the reset values of the PDRUNCFG and SYSAHBCLKCTRL registers. The power
configuration can be changed during run time.
