The LPC1850/30/20/10 support four reduced power modes: Sleep, Deep-sleep,
Power-down, and Deep power-down.
The LPC1850/30/20/10 can wake up from Deep-sleep, Power-down, and Deep
power-down modes via the WAKEUP[3:0] pins and interrupts generated by battery
powered blocks in the RTC power domain.
Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug and
trace functions are supported in addition to a standard JTAG debug and parallel trace
functions. The ARM Cortex-M3 is configured to support up to eight breakpoints and four
watch points.
