The RGU allows generation of independent reset signals for individual blocks and
peripherals on the LPC4350/30/20/10.
The LPC4350/30/20/10 feature several independent power domains to control power to
the core and the peripherals (see
alarm timer, the CREG block, the OTP controller, the back-up registers, and the event
router) are located in the RTC power-domain which can be powered by a battery supply or
the main regulator. A power selector switch ensures that the RTC block is always powered
on.
The LPC4350/30/20/10 support four reduced power modes: Sleep, Deep-sleep,
Power-down, and Deep power-down.
