LPC5411x
32-bit ARM Cortex-M4/M0+ microcontroller
generates an RTC wake-up interrupt request, which can wake up the part. During deep
power-down mode, the contents of the SRAM and registers are not retained. All functional
pins are tri-stated in deep power-down mode.
Table 8
shows the peripheral configuration in reduced power modes.
Table 9 shows the wake-up sources for reduced power modes.
