LPC5411x
32-bit ARM Cortex-M4/M0+ microcontroller
After power-up, the temperature sensor output must be allowed to settle to its stable value
before it can be used as an accurate ADC input.
For an accurate measurement of the temperature sensor by the ADC, the ADC must be
configured in single-channel burst mode. The last value of a nine-conversion (or more)
burst provides an accurate result.
7.23 Emulation and debugging
Debug and trace functions are integrated into the ARM Cortex-M4 and ARM Cortex-M0+.
Serial wire debug and trace functions are supported. The ARM Cortex-M4 is configured to
support up to eight breakpoints and four watch points. The ARM Cortex-M0+ is configured
to support up to four breakpoints and two watch points. In addition, JTAG boundary scan
mode is provided.
The ARM SYSREQ reset is supported and causes the processor to reset the peripherals,
execute the boot code, restart from address 0x0000 0000, and break at the user entry
point.
The SWD pins are multiplexed with other digital I/O pins. On reset, the pins assume the
SWD functions by default.
